I am experiencing a bizarre problem. When I enter Edit mode, the content of my Confluence page appears in a tiny sliver of a window with the bottom footer bar of the Confluence interface filling about 7/10ths of the screen (see screenshot).
I can scroll the content of my page and edit it, but only in a tiny slice of screen space. What has happened? Have I inadvertently hit some secret key command to expand the footer panel? How do I revert to a usable layout?
I have tested this in multiple browsers, in Incognito/private mode as well, and still have this issue.
