I think there are three separate issues conflated here:
- request to disable auto-scroll when (while dragging the dialog) mouse is near top or bottom edge of the viewport
- from the forum post, request [for option] to restrict dialog dragging within bounds of viewport, using constrainedMovable
- some other issue I see when moving the mouse to the right; even when autoscroll is disabled, having the dialog at the right makes the document wider, showing a horizontal scrollbar. Not such a big issue.
I have a patch for #1 which I'll attach, although I'm not sure I should check it in, maybe the auto-scroll is actually useful when there's a Dialog? In any case I don't see how the current behavior is a problem, maybe you can explain?
For #2, I don't see the urgency either, actually being able to move the Dialog partially off-screen is often important so the user can see the content behind the dialog.
As for #3 that doesn't seem important.
So, I'll leave this open to consider for 1.6, but will likely close as wontfix.
