Browser issue Responsive image expansion

[Hornstar]

I was here http://xenforo.com/community/resources/donation-manager.385/

I double clicked the image to expand it. All good. Now double clicked to shrink it but only half the page went back to normal and the other half shrunk a heap more. I've tried a few times and each time was a bit glitchy.

That looks like a redraw issue to me, which seems like a browser bug. Presumably scrolling around or rezooming should fix it (though I suppose note if they cache the output more).

The only way I could fix this one was by refreshing. Zooming in and out had no effect unlike other times.
