bug#46238: 27.1; recenter-top-bottom in fullscreen

[Colin Okay]

When in fullscreen mode, recenter-top-bottom fails to toggle to the
"bottom" position. Pressing C-l with the cursor at the top will recenter
the window with the cursor in the middle, pressing it again does
nothing, and pressing it one more time will recenter the window with the
cursor at the top. The quirk is not present when emacs is not in
fullscreen mode.
