Every time I want to change the color of an existing highlight (or edit its start/end handles), after I change the color, the page shifts up or down to some kind of "default" viewing position for the highlight.

I'm not sure why, because it doesn't shift the viewport when I select the highlight or anything. It's only after changing it.

It's super annoying though and I can't think of any good reason for the unexpected scrolling, so I'm classifying this as a bug.

I make 100's of highlights a day as I read, and often change my mind about the color after highlighting, so this happens to me constantly.

Please -- if you can just find the code after an annotation has been modified that calls some kind of scroll/reposition function and delete the call... that would fix it! Again, I've never experienced this scrolling in any other situation where it would be desired, so it seems to be just a complete bug.

(Note: I read PDF's in continuous mode, obviously this wouldn't happen in single-page.)
