Thanks for the patch.  My initial reaction is that I'm not sure about
adding an idle timer for a particular aspect of fontification.  If we do
go this route, I think the case needs to be made why this spot is
special, and why we don't expect or would reject follow-up patches for
this and that other area.

Have you explored whether jit-lock (e.g., jit-lock-defer-time) helps for
your use case?
