When I tested locally, IE11 had the same problem like Firefox, but Edge did not have the problem.

Is the screenshot really taken on IE? Isn't it taken by Edge, is it?

Bug 1022553 seems like very similar problem and this bug seems like default behavior or Firefox. It is commented at Bug 1022553 Comment 2 like the following

With comment 6, it seems not a graphic problem.

Move the component to layout with comment 7.

This bug seems like dup of bug 1266172

Moving to p3 because no activity for at least 1 year(s).
