-----------------------------------------------------------------------
I think the wording of this issue is too vague. The mailing list discussion
where this arose involved mouse clicks _to enable/disable line breakpoints_
(and perhaps similar actions but that's a concrete example I can verify).
Regarding that specific situation:
It's standard behavior of UI buttons to activate on the mouse up, but only if
the cursor is not moved off the button between the mouse down (which must occur
on the button) and the mouse up. The breakpoint click target area appears to me
to behave like an invisible button. I don't know if that's the intention, but
if so, it departs from the standard button behavior I just described in the
following way: if _any_ change in cursor position happens between the mouse
down and mouse up the activation does not happen, _even if the position at
mouse up is still within the invisible target area for the breakpoint_. This is
the aspect of its behavior that is problematic.
