Customize widgets: Link Popover not visible in full (Entire toolbar not visible)

[arunsathiya]

Description

On a theme with block widgets, the toolbar on the widgets area of the Customizer is not visible in full. It gets cut in the middle, with half appearing outside of the display area.

Step-by-step reproduction instructions

• Start with a theme that has block widgets, like Twenty Twenty-One or Espied.
• Open the site's Customizer and click on the widgets area.
• Add a list block, or any block.
• Choose the text on the block and add a link.
• Notice that the toolbar that pops up to add the link does not appear in full.

I did my best to locate an existing issue with keywords like block widget toolbar and missing but can't spot one so far. Happy to be pointed at a report, if one exists already.

Closing this issue in favor of this one since that is already being looked at there.

@Thelmachido From our testing, it looks like a core bug though, which is why I created this issue. Could we reopen this issue?

Re-opening as I can replicate with GB 13.5 RC 1, WP 6.0, and TT1:

While it can be investigated in a separate repo for third party work, it's definitely important to track down the root cause in Gutenberg here, since something seems amiss!

Is it the Link popover that's cut off? The issue title says toolbar, but it's ok in the screenshots.

edit: Seems so, I've updated the title.
