Internet Explorer - snackbar does not disappear (a gray rectangle is visible afterwards)

[Esadruhn]

Current behaviour

Internet Explorer 11
I change the resolution to 1280x1024 and zoom out

I get a snackbar to open ("Veuillez sélectionner un ensemble d'aides")

I close it. A grey rectangle stays on the page. It does not go away even if I refresh the page.
When I navigate in the app, it stays there. If I open the app in another tab; I can see it.

Expected behaviour

When I close the snackbar it disappears
