Navigation and Tab toolbars do not appear when hovered near top in fullscreen mode

[yuminya]

Normally in base PM when you hover on top of the screen during full screen, Tab and Navigation toolbar should appear (with address bar and all).
After installing this addon, this hover behavior is no longer possible. Tested with no other addons enabled and fresh profile on PM32.
This makes it difficult to operate in full screen.
The only possible "fix" I found was to have those bars always visible in full screen, but that kinda defeats the purpose of using full screen to begin with.

Hopefully it is possible to bring back this mouse hover behavior back.
