render: resize: fix crash when reflowing the alt screen

Browse source 
When doing an interactive resize, and `resize-delay-ms` > 0 (the
default), we would crash if the original screen size (i.e. the size
before the interactive resize started) was larger than the last window
size.

For example, if we interactively go from 85 rows to 75, and then
non-interactively went from 75 to 80, we’d crash.

The resizes had to be made in a single go. One way to trigger this was
to start an interactive resize on a floating window, and then *while
resizing* toggle the window’s floating mode.

Closes #1377
