Filament v5.7 — modal open/close scroll-jump reproduction

Minimal reproduction for a scroll regression introduced in Filament v5.7.0: interacting with a modal (opening or closing) scroll-jumps the page when the document is the scroll container.

Versions

• filament/filament v5.7.1 (regression introduced in v5.7.0; last good: v5.6.8)
• Laravel 13, Livewire 4, PHP 8.4

Setup

composer install
cp .env.example .env
php artisan key:generate
touch database/database.sqlite
php artisan migrate
php artisan serve

Then open http://127.0.0.1:8000/admin/repro (auth is disabled in this repro for convenience).

Steps to reproduce

1. Scroll down so the orange “Open confirmation modal” button is near the top of the viewport but still visible (the scrollY badge, top-right, reads > 0).
2. Click the button to open the confirmation modal.
3. Watch the scrollY badge: the page scroll-jumps (the modal's focus management scrolls the document). Closing via Confirm / Cancel / Escape does not restore the position.

Expected: opening/closing the modal leaves the scroll position unchanged. Actual (v5.7.x): the page scrolls.

Note: the exact direction/magnitude is browser- and layout-dependent (Chrome uses block: "nearest" for focus scrolling). The scrollY badge makes any jump measurable. In real apps this shows up most visibly as the page jerking toward the top when a modal closes, because focus returns to the top-anchored main.fi-main (tabindex="-1").

Cause

The modal component's focus trap lost the .noscroll modifier in v5.7.0.

vendor/filament/support/resources/views/components/modal/index.blade.php

- x-trap.noscroll{{ $focusTrapReturnsFocus ? '' : '.noreturn' }}{{ $autofocus ? '' : '.noautofocus' }}="isTrapActive"
+ x-trap{{ $focusTrapReturnsFocus ? '' : '.noreturn' }}{{ $autofocus ? '' : '.noautofocus' }}="isTrapActive"

x-trap's focus activation/restoration calls .focus(), which scrolls the element into view. .noscroll previously suppressed this. It appears to have been dropped while moving scroll-locking into Filament's own JS (likely for the nested-modal stuck-scroll-lock issue, #10925 / alpinejs/alpine#3435), which also removed the scroll suppression.

Confirmed fix

Editing that one line to re-add .noscroll (or calling the focus restoration with { preventScroll: true }) eliminates the jump — verified in this exact reproduction: with .noscroll the modal opens with scrollY unchanged; without it, scrollY jumps (e.g. 687 → 1691).
