mouseWasDraggedSinceMouseDown() true when clicking slowly

e.mouseWasDraggedSinceMouseDown() is always true in mouseUp() if I don’t click fast enough.

This is on mac, using the trackpad, doing a real click (not a tap), without moving at all my finger, and I don’t think I’m clicking that slow… just a normal click really.

As a result I often have to click several times on labels to enter in edit mode (for instance in the properties components), and that is quite annoying…
Not sure if that’s something that has changed in mojave and if there’s anything that can be done to ‘relax’ that time constraint?
