BUG: Selection box stays in certain case

[Stringer]

Is it just me, or does the selection box stay on screen if you drag it to the very bottom of diagram and then release?

Steps to reproduce:
1) create a diagram
2) click and hold left mouse button from center of the diagram screen
3) drag mouse cursor (while holding the button) to the very top of the diagram
4) release the button

Same works also for left and bottom edges. For some reason bottom shows this behaviour if you drag from right to left, but not from left to right. Other edges don't have such requirement, they always fail to hide the box.

I also see the dotted frame stay on screen when following above steps. You should send a bug report.
