3.0 Quick reference window losing it's sizing w/ composition mode

I open a document in quick reference in order to put it overtop of my document when it’s in composition mode so that I have access to notes while drafting. The size it opens into by default seems static, the same every time. I resize it to what I want.

Then I hit F11 for composition mode, which works normally. However the quick reference window, that otherwise behaves exactly as expected, resizes. I have to resize it back down to what I had it at.

Then when I leave composition mode, same thing. Going in and out of composition mode resizes the quick reference window frame every time.

Using version 3.0.0.0
