User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:93.0) Gecko/20100101 Firefox/93.0

Steps to reproduce:

In the Bookmarks side panel, I typed a search term into the Bookmarks search window.

Actual results:

The bookmarks list was purged to show only terms related to my search (as expected.) But the "X" button to close the search results and restore the full bookmarks list is now missing.

Expected results:

The "X" button to close the search results in the bookmarks search window should appear on the right side of the search window, as it used to in former versions.

Without this needed Close button, the only ways to restore the full bookmarks now is to manually delete the entered search term, or to close the bookmarks side panel entirely and then reopen it.
