"Exit Fullscreen" button doesn't disappear when I switch to workspaces

Description of Problem:

When I activate Epiphany's full screen mode, an "Exit Fullscreen" button
appears at the lower leftmost corner of the workspace I'm working in.
Not only does this button prevent me from reading text on the browser,
it also appears on every workspace I switch to, as long as Epiphany
remains in "fullscreen mode", thereby also preventing me from reading
text from the bottom panel or other applications. 

Steps to reproduce the problem:

1. Launch epiphany
2. epiphany menu -> view -> fullscreen
3. switch workspaces
4. observe the "Exit Fullscreen" button at the lowest leftmost corner of
the workspace or the browser

Actual Results:

"Exit Fullscreen" button appears on every workspace I switch to. It also
prevents me from reading text on in the bottom panel, in epiphany and in
other applications.

Expected Results:

I expected the "Exit Fullscreen" button to disappear after a few seconds
and only reappear if I triggered it via moving the mouse towards its
direction or other keyboard manipulations. 

How often does this happen?

Always

Additional Information:

Although this may be against your useability policies, It will be nice
to provide an option to hide the "Exit Fullscreen" button by right
clicking on it and choosing hide from an option menu. If this violates
your useability policies, you may promptly discard the idea.
