Two things, both reported from the running app.
Nested modals could not exist. Mantine binds a window-level keydown listener
per open modal, gated only on whether that modal is open -- nothing checks which
one the user is looking at:
useWindowEvent('keydown', (event) => {
if (event.key === 'Escape' && closeOnEscape && ... && opened) onClose();
}, {capture: true});
Two open modals meant two listeners, so one Escape closed both. Reproduced on
the dashboard: the download modal plus the search modal over it, one press, both
gone, back to the page. Both also sat at z-index 200, so which one drew on top
was DOM order rather than which the user opened.
Mantine's own answer is Modal.Stack with a stackId, which is the only thing that
gates closeOnEscape. Not used, for two reasons: every call site would have to
be rewritten to hoist its modal into a stack, and it sets `__hidden` on
everything below the top -- the parent disappears while the child is open. The
parent should be dimmed and still there, as it was before the migration.
So the wrapper keeps the register itself: a module-level list of open modals,
most recent on top, from which each modal takes closeOnEscape, trapFocus and a
z-index two above its parent. Module-level rather than React context because
the two modals in the bug are not nested in the JSX at all -- the search modal
is rendered by KeyboardShortcutsProvider near the app root and the download
modal by the dashboard. They are siblings that happen to be open together, and
no context relates them. The increment is small on purpose: Mantine puts
popovers at 300, and a stack that climbed past it would paint over the select
dropdowns inside its own forms.
Widths: Roland audited the modal list and chose sizes against Mantine's scale.
Sixteen get wider -- twelve to `large` (620), four to `fullscreen` -- and eleven
keep the width they had, with the size now written down so the decision is in
the source rather than in a default. Flasher was passing Mantine's raw `sm`,
which worked but bypassed the naming the audit used; it says `tiny` now.
The size table itself is guarded, because it is the single thing that halved
every modal during the migration and a quiet edit to it moves seventy at once.
Semantic's widths, measured on the pre-migration build still running on the QA
Pi: mini 360, tiny 540, small 720, large 1080, no-size 900. Mantine's, read out
of its stylesheet: 320/380/440/620/780. A `small` modal went 720 -> 440 and one
with no size went 900 -> 440. Three cases now hold the scale, the mapping, and
the rule that no call site may name a size the table does not know -- an unknown
name is passed to Mantine, ignored, and silently rendered at the default.
Tested in a real browser: none of it is visible to jsdom -- the listener is on
window with capture, the stacking is z-index, and "still visible behind" is
geometry. Note that `should('be.visible')` is the wrong assertion for the
parent: it is an occlusion check, so a child drawn correctly over its parent
trips it. The test uses a wide viewport and asserts the parent is rendered and
shows to both sides of the child. Planting the pre-fix behaviour reddens three.
1124 jest / 62 suites, 8 in modal-stack.cy.js, clean npm run build. The 12
failures in Tags/Channels/Download/Inventory.cy.js are the known pre-existing
Semantic-era selector failures, unchanged.

Getting Started with Create React App
This project was bootstrapped with Create React App.
Available Scripts
In the project directory, you can run:
npm start
Runs the app in the development mode.
Open http://localhost:3000 to view it in your browser.
The page will reload when you make changes.
You may also see any lint errors in the console.
npm test
Launches the test runner in the interactive watch mode.
See the section about running tests for more
information.
npm run build
Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.
The build is minified and the filenames include the hashes.
Your app is ready to be deployed!
See the section about deployment for more information.
npm run eject
Note: this is a one-way operation. Once you eject, you can't go back!
If you aren't satisfied with the build tool and configuration choices, you can eject at any time. This command will
remove the single build dependency from your project.
Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right
into your project so you have full control over them. All of the commands except eject will still work, but they will
point to the copied scripts so you can tweak them. At this point you're on your own.
You don't have to ever use eject. The curated feature set is suitable for small and middle deployments, and you
shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't
customize it when you are ready for it.
