Cannot add annotations in "full page" (fullscreen) mode.

[aaichert]

When switching to "full page" (fullscreen) mode using the beveled round "Toggle full page" button, it is no longer possible to add annotations, even when "c" is pressed on the keyboard or annotation mode is on before pressing the button.

(tested on chrome, firefox and safari on ipad)

Dear user,

thank you for the bug report. I´m able to reproduce the error and will fix it a sone as possible,

In the meantime, with the following option, you can create some sort of full screen that works.
