Forgive me if this is the wrong place to report a bug or similar apparent issue, I did try to find that proper location.
On timeline view for the past few weeks I’ve occasionally gotten a popup from a dependency line that won’t go away. See screenshot. I’ve had times that matter where I click on the screen, that popup just stays there and I have to reload the browser (Chrome, on Windows 11). Obviously not a game breaker or anything but it can be a bit annoying.
The popup happens any time you hover (intentionally or otherwise) over a dependency line.
