favicon not saving

[Tritonus]

Content-> Configuration-> Edit->Html Head->Favicon Upload.

It says "Allowed file types: ico, png, gif, jpg, jpeg, apng, svg. Not all browsers support all these formats!"

When I select an .ico file to upload it says 

"

Attention

We don't recognize or support this file extension type.

I would convert it to a png or gif personally.
