It's:

Debugger entered: nil
  x-handle-reverse-video(#<frame GNU Emacs at xo 0x55a6e4722360> ((vertical-scroll-bars) (height . 53) (width . 81) (reverse . t) (cursor-color . "red") (cursor-type . box) (mouse-color . "red") (horizontal-scroll-bars)))

Indeed.  I tried to do some VC history spelunking for why we're
apparently checking reverseVideo redundantly in this way, but I came up
short.

It might not be redundant on Windows, which presumably doesn't call
these X functions, but does heed reverseVideo in the w32 version of
window-system-initialization.
