Bug Summary

I use the auto-hide feature for the bookmarks bar. Within the first 3 days of using the browser, bookmarks disappeared once. Instead of them, an empty bar appears. Yesterday, this started happening frequently. I don't see any particular reasons for this. Just regular browser use.

Also, I use a tab panel on the left with auto-hide, showing only icons. Lepton UI + Pop! Dark theme + Orange Highlights.
