Yes, that's correct, I think.  But shouldn't it be smarter here?  That
is, the display engine does know that all the text it inserted was
invisible, so calling jit-lock again (with the same parameters as
previous time) is futile.

However, this is probably not something many modes do, so putting more
effort into optimising this is probably not worth it.

Probably.
