Again, why is it our problem?  If the user wants to have this sequence
for some reason, it is up to the user to select the font that displays
this properly.  Emacs has no business preventing users from typing
nonsensical sequences of codepoints.

I'm not sure this is related.  As I wrote, it is okay for the input
method not to support more than one tonos following a base character.
But that does not (and should not) prevent the user from typing as
many tonos accents as he/she pleases by other means.  The only
requirement from Emacs is not to crash as result of displaying such
sequences.
