Hello.

With current master:
1. emacs -Q
2. C-h i m Emacs RET
3. Type SPC.  I see some garbage text on the buffer.
For example, I can see part of the title "The Emacs Editor", and it stays
if I keep
typing SPC.

I have only managed to reproduce this in Info buffers.

Best regards,
Mauro.

This was due to a stupid typo I made in one of my recent commits,
which Martin already fixed on the release branch.

Ah, I see.  Apologies, I should've checked the emacs-27 branch too.
