browser hangs when clicking in bookmarks window
Steps to reproduce:
- Bookmarks -> Show All Bookmarks
- Under the "All Bookmarks" heading in the list on the left side of the window, click on "Bookmarks Toolbar" or "Bookmarks Menu"
Expected result: Seeing the contents of those subfolders in a timely fashion.
Actual result: Entire browser stops accepting keyboard and mouse input for ~30 seconds. Browser may remain sluggish afterwards until relaunched.
The other items in the list do not exhibit this problem, just those two subfolders.
I have observed this on SubgraphOS (Debian, using xpra as an X proxy) but someone in the #subgraph channel reproduced it without xpra too.
