Description

In the Navigation Block toolbar, the "Select Menu" button opens a dropdown from where a different menu can be selected. Selecting a menu from that dropdown causes the dropdown to close, but when it closes keyboard focus is reset to the document body.

Focus should instead go back to the "Select Menu" button in the toolbar, or perhaps to the block itself.

Possibly due to #39044

Edit: Now it only happens when creating a new menu or importing from a classic one.

Step-by-step reproduction instructions

1. Create a Navigation block, and make sure the site has more than one navigation menu already.
2. In the Navigation block toolbar, click "Select Menu" and choose a menu from the dropdown.
3. Note focus is no longer on the block when the dropdown closes.
