No, no chance. That bug was system-independent, while this one is
specific to macOS. Also, while investigating bug#63186, I've
established that disabling scrolling_window optimization doesn't fix
the problem with redisplaying the mode line after mode-line-format was
nil.

Not that I know of, and so if Po Lu's suggestion fixes the problem,
we'd need to understand how come scrolling_window fails on macOS.
