[Bug]: Regression ARIA snapshot controls/selection appear behind Angular Material Dialog (cannot see what is snapshotted)

[terradek]

Version

1.58.1

Steps to reproduce

When using the Playwright VS Code extension to capture an ARIA snapshot on a page with an Angular Material MatDialog open, the extension’s ARIA snapshot UI (buttons, selection overlay/feedback) appears behind the modal. As a result, it’s not possible to see which element/region is being snapshotted while the dialog is visible.
This is reproducible on Angular Material’s official dialog examples page.
Navigate to Angular Material dialog examples: https://material.angular.dev/components/dialog/examples.
Click “Open dialog without animation” (or any “Open dialog”) to show a modal dialog.
In the Playwright extension’s Locators/ARIA panel, attempt to pick or preview an ARIA snapshot for the dialog content (or for body).
Actual: the ARIA snapshot UI (buttons/selection highlighting) appears behind the modal dialog, making it unclear what aria tree is being captured, and preventing practical use.

Expected behavior

The Playwright VS Code extension’s ARIA snapshot UI and selection/highlight overlays should remain visible and on top of application UI (including modals), so users can see which node/region is being snapshotted and operate the controls.

Actual behavior

With MatDialog open, the extension’s ARIA snapshot UI/overlay appears behind the dialog. The snapshot may still be captured, but users cannot see what is selected or interact reliably with the UI.

I guess this dialog is presented in the "top layer" and our highlight is behind it. We should probably move highlight to the top layer whenever available/needed.
