Text stretched after closing word study tab

When I launch a bible word study, and the tab opens next to an existing tab, the text from the existing tab will stretch across the view rather than re-layout once I close the bible word study tab.

I've attached three images. The third one showing the result is sized differently because I found I had to do a full refresh and then follow the steps to make it happen consistently. If I touch the browser to force a resize and then try, it seemed to sometimes work okay.
