Original change's description:
> [Bookmarks] Fix opaque background behind bookmark dialogs on tablets
>
> On large-screen Android devices such as foldables and tablets, the
> bookmark edit and folder picker activities are presented as floating
> dialogs. A recent change to the edge-to-edge layout caused these
> dialogs to expand their decor bounds and paint over the dimmed
> browser UI, leaving a completely black backdrop.
>
> The issue stems from the edge-to-edge layout being disabled only
> when the desktop bookmark dialog flag was enabled. On tablets, the
> activities would draw edge-to-edge, expanding the floating dialog
> bounds. Furthermore, the DialogWhenLarge theme lacked the translucent
> window attribute on large screens, causing WindowManager to treat the
> activity as occluding its parent. This stopped the parent tabbed
> activity and hid its compositor surface.
>
> To fix this, the translucent window attribute is added to the
> DialogWhenLarge theme for large screens. Additionally, the bookmark
> activities now override the edge-to-edge creation and layout wrapping
> methods to opt out whenever they are presented as a dialog. This
> ensures the underlying browser UI remains visible and appropriately
> dimmed.
