GCode slider stops working when cursor leaves window

[dunkmann00]

Description of the bug

When dragging the GCode slider (the one on the bottom), if the mouse happens to leave the PrusaSlicer window it will stop traversing through the GCode and start rotating the view instead. I would expect it to continue to traverse the GCode as long as the mouse button is still pressed.

This behavior is not present on 2.7.4.

It seems my original assessment was not completely correct. I'm only seeing this happen when quickly moving the mouse off the screen (which was happening when I scrolled through the GCode quickly). But if I slowly move the mouse out of the window the problem does not happen.

I am also now noticing that if I drag the bottom GCode bar's handle all the way to completion (at the right) and then try to drag it backwards, it does not work unless the mouse is inside the scroll handle. If it is above it, it will stop moving, but can be reactivated by moving the mouse inside the handle.
