Well I'm in the process of writing a script that's got pretty heavy right-click menu interaction and upon using the build in interaction method it appears the menu can get left by the mouse very commonly, it seems that the average success rate is 40-50% but I've noticed at times it can leave the menu and fail the interaction 6+ times before any success.

Just a note of a related topic I found from several years back with seemingly the same issue;
Resolved - Clouse inaccuracy for menu options



Edit: Appears solved in todays update
