When I went to adjust the bottom of the window by dragging, the window expanded right to the bottom, such that I couldn't see the search pane. I dragged the window to my second, larger monitor, but it expanded further, same deal. Dragging it back to my 1st monitor did not reduce it back at all, so after a couple of goes of this, I felt like I was in the middle of a bad fairytale, with the window getting larger and larger each time.
Of course, every time I go to the bottom of the screen, I get the popup dock, but that's why I wanted to manually expand it to just a bit less.
The way I resolved it was to call up the workspace again, recalling my original (and closing the expanded one).
