The combined behavior of the mouse and "scroll-margin" is a bit odd
currently.
If you have a buffer which has "scroll-margin" enabled, and you click
anywhere in the scroll-margin region, the point is moved and the buffer
is immediately scrolled.
This in turn often results in the click becoming a "drag" instead,
selecting parts of the buffer.
I rarely use the mouse, but when I do (usually in customize groups, or
when using eww), it trips me all the time since I use a rather large
scroll-margin.
If feels like that moving the point when using the mouse shouldn't
trigger scroll-margin ever, since any action that causes a scroll would
immediately move the current target away and result in unintended
behavior. I can see the same effect when performing a selection by
dragging: once you reach the scroll-margin area every single motion
events selects half the visible buffer, which is also broken.
