The side sheet, the bottom sheet's panel and the docked search's scrim and view kept `display` alive through their exit with `transition-behavior: allow-discrete`. Firefox does not transition `display` (Chrome 117 and Safari 18 do), and `x-show` sets `display: none` in the frame the exit starts, so in Firefox the sheets vanished instead of sliding out and the search view and scrim vanished instead of fading. The docked search had a second problem in every engine: neither the view nor the scrim had a closed state to transition to, so where `display` was held (Chrome, Safari) the view stood at full opacity for its duration and then disappeared. Each element now carries `x-transition:enter`/`:leave="md-transition"`, the approach the two sheet scrims already took (renamed from `md-scrim-transition` to one name for all of them). The class only switches Alpine to CSS-transition mode, so `x-show` holds `display` for the element's computed transition-duration before hiding it, in every engine, and a reopen during the exit cancels the pending hide; nothing styles it. `display` and `allow-discrete` leave the transitions so Chrome and Safari do not hold a second time. Alpine reads the first `transition-duration` listed, which is the closing slide or fade in each list (the preset panel lists translate before height). The search view now closes back into the bar (opacity 0, `scale: 1 0.9`, the reverse of its `@starting-style` entry) and its scrim fades out on close and when the search turns full screen. Under reduced motion the durations are zero and every one of them closes at once. Four browser tests sample each exit mid-way in the page, in the same round trip as the close: the sheets part of the way to their closed offset, the search scrim and view part of the way faded, each still displayed, then `display: none`. All four fail on main in Firefox (the two search tests in Chrome too) and pass in Chrome, Firefox and Safari. OverlayTest pins the drawer's new transition and the view's markup.

/*
|
|
* M3's search: a search bar that opens into a search view (SearchBarTokens, SearchViewTokens,
|
|
* androidx Compose Material 3, Apache-2.0).
|
|
*
|
|
* The bar is a 56px pill in surface-container-high: a leading search icon, the input in
|
|
* body-large, a clear button once something is typed, and whatever the caller trails it with (an
|
|
* avatar, an icon button). Focus opens the view. On a medium or wider window the view is docked
|
|
* over a scrim: the bar grows down into an extra-large-cornered container at elevation 3 that
|
|
* holds the results. On a compact window it takes the whole screen, and the search icon turns into
|
|
* a back arrow. `docked` keeps it docked at every width.
|
|
*
|
|
* Widths are M3's: never wider than 720px, and the bar grows to that width while it is focused —
|
|
* `--search-width` is its resting width (the room it is given, by default) and
|
|
* `--search-open-width` the focused one, so a caller that wants M3's 360px resting bar sets
|
|
* `--search-width: 360px` on a wrapper. The leading and trailing padding is 24px unfocused and
|
|
* 16px focused, as the search specs table gives it.
|
|
*
|
|
* Hovered and focused buttons in the bar take M3's state-layer opacities (tokens/state.css), and the
|
|
* docked scrim is M3's scrim role at 32%, which no system token names. The breakpoint that makes the
|
|
* view full screen is decided in resources/js/search.js (`upTo('medium')`, 600px).
