If we go with my suggestion for the next patch to not reset display info
for panels, then this problem disappears. Because all the stuff you
identified as static is relevant for panels, and for panels _everything_
is static.
I think with the next patch changed per my suggestion you could drop this
one here outright, and still retain all the benefits of your cleanup.
