Widget overlap when scrolling a content-view horizontally

We have a content)-view with a lot of columns. When it is scrolled horizontally to the right, to display more columns, some fields on the left overlap (with the tree-view and the space below).
In my example it is only the vocabulary tag (see the attached mp4).

Our prospects say they have the problem with IE 11 too.

Waiting for a fix, a quick workaround would be welcome
