Fontification of prettified symbols

[wedens]

With (setq prettify-symbols-unprettify-at-point 'right-edge) prettified symbol loses its face property after the cursor is placed on it:

There is no such issue in other major modes, so it must be something happening in scala-mode specifically.

My setup is basically the same as https://github.com/hlissner/doom-emacs/blob/develop/modules/ui/pretty-code/%2Bfira.el#L6

Emacs 27.0.50
scala-mode 56cba29

I think the problem is that when prettify-symbols-mode tries to re-fontify the symbol, it doesn't have context (and => seems to be fontified contextually):
(apply #'font-lock-flush prettify-symbols--current-symbol-bounds)
