Downsizing pdf-panes doesn't work

[0x4c46]

It is hard to downsize panes in which PDFs are open. It only works, if you are moving your courser very slow, so that the courser isn't hovering over the PDF. The same issue appears in standard theme, but it's handled better there because there is a tiny bit of space around the PDF, so you can move your courser faster while downsizing.

Maybe you can do the same until it's fixed.
