fix: group selection functionality (multiple issues)

[meetzaveri]

Issue 1 - In group selection arrow component changes the direction
When you use group selector to select area containing arrow, the arrow on group selection , changes it direction to opposite.

Issue 2 - In group selection area, the component doesn't get selected
So if I draw a group selection area consisting of rectangle and circle, only rectangle will be selected.

Update:

I've fixed Issue 2 as mentioned above. But there exists a problem is that if user performs group selection from either top-right, bottom-right or bottom-left, it will not work.
