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.
