I think the issue here is that
RectangleHandle.HasDragged()does the comparison in view coordinates, so when zoomed in these are scaled up and the delta can become larger than the tolerance. At least with a touchpad, I saw a slight variation in the mouse positions between the mouse down and mouse up events, so this is amplified with the scalingProbably this should instead just check whether the resulting rectangle is empty, since that's really what we care about

Hi @cameronwhite , I’d like to try solving this issue, do I need to be assigned? This is my first ever open‑source contribution so it might take a bit longer than exptected.

thanks for the interest! You can assign yourself but it's not strictly necessary.
There was a previous attempt at fixing this in PR #2022, so definitely should have a look at the changes and discussion there

I realized PR #2022 is still active, so I’ll step back from this issue.
