Can't grab the Adobe PDF window on the top left

I typically work with an external monitor when using my laptop. When I disconnect the monitor, some application windows reappear on the far right side of my laptop screen.

For most programs, I am able to reposition these windows by clicking and dragging from the top left corner. However, in Adobe Acrobat, the menu bar occupies this area, preventing me from grabbing and moving the window back into view.

Would it be possible for the program to provide a small accessible area in the top left portion of the window frame, so that the window can be easily repositioned when this situation occurs?

Worst case, the pdf is already at its maximum window size, and I can't even use the resizing of the size by grabbing the corner sometimes...
