13.2.0.230 Editor's bookmarks

When I delete the line (Ctrl+Y) above the bookmark, the bookmark indicator disappears. I can still go to it - it is just gone from the gutter.
The bookmark reappears when I create a new line just above it, or start typing on the line above it.

Interesting. It took me a bit to reproduce, but I see what you mean. I will log this.

Resolved in 13.3.0.34 (at least I cannot reproduce it)
