Idea: Avoid triggering popup menu action from mouse-release shortly after mouse-press
On Windows, popup menus appear when releasing the right-click button. On MacOS, they appear when pressing the right-click button. FlatLAF correctly follows this behavior on each platform.
There's a usability problem on MacOS, though. If the user moves the cursor towards the intended menu item, and happens to release the mouse button while the cursor is now over another menu item, then the latter action will be executed instead of the intended one. I make this mistake myself quite often when working quickly (with an external mouse, not a trackpad). See the screen recording below:

Proposal: In a JMenuItem, ignore a right-button mouse-release event for action triggering purposes if it comes within a short duration of the corresponding mouse-press event (e.g. 250ms).
But isn't this a general "problem" when using right-mouse-press-hold-and-move-and-release on macOS. This can also happen in any native macOS app, right?

Not sure whether this would help 😕 I mean you can accidentally release the mouse button also after the 250ms...

Yes, correct! This would be an improvement over MacOS defaults. Just a bonus feature, so to speak. (I considered implementing it myself and submitting a PR, but thought I'd solicit your opinion.)

There's a certain threshold of time before which it is reasonable to assume that the user is trying to click, rather than drag. Above that threshold, it is reasonable to assume the user is trying to drag.
