Subject: [PATCH] Widgets: Improve theme styling compatibility for Custom HTML
 widget by adding container with `textwidget` class.

The same styling from the Text widget should apply to the Custom HTML widget since users are expected to copy HTML from the (legacy) Text widget into the latter.

Amends [40893].
See #40907.
Fixes #41392.
