TinyMce: the editor appears without space between the icon groups. Once resizing the editor you can not go back to this state.

We may want to get rid of this no-space version or we may want to keep it (maybe tweak it a bit so it looks like one group => i.e no rounded border in the middle icons).

In the current state as the user is not able to go back to the original state, (s)he will consider it as a bug.
