Initially adding a bookmark in Brave works fine, but when I try to edit the title or other elements of the bookmark, it is nearly unresponsive. I have to wait for about half a minute and see where the cursor lands, then wait for several seconds each keypress to know what’s happening.
Eventually, I’ve been able to get the bookmark edited, but something is severely mixed up there.
Running MacOS Sierra 10.12.6, and fwiw I have a dozen or so tabs open, but I’m pretty sure it’s happened even when I don’t. This has been repeated behavior every time I’ve tried with bookmarks.
