I am currently working on a dialog window that is positioned over the whole page and consists of 3 parts - the head part, the content part and the foot part. The dialog window itself has a maximum-height.
The head and foot parts have a fixed height. The content part wraps around its content and grows / shrinks with it. If the content exceeds the maximum-height of the dialog window, it should become scrollable.
The whole thing is built with a flexbox and works just fine in FF and Chrome. Unfortunately the client needs to have it working in IE11 aswell, but this causes a to me unknown bug - Everytime the user moves the mouse in to / out of the content (which should be scrollable), the container breaks out of its overflow and bounces back in.
I could imagine that flexbox and scrollbars don't get along with each other well in IE11 - but I couldn't find any related issues in the web.
Is such an issue already known?
Thanks in advance
