Thanks for the report.

This is not a duplicate of bug 1165611, because here the wrong font is used.
It may be the same issue as bug 1165788, but best I think to keep reports separate until the cause is identified.

Can you paste the output from these commands please?

  fc-match -s sans:lang=th | head -n 10
  fc-match -s serif:lang=th | head -n 10

Waree seems reasonable as the first match here, though some of the others near the top of the list are surprising...

...but why on earth does fc-match offer a bunch of Indic fonts here?

Instead of Waree the wrong font being used is FreeSerif.

Setting following pref restore the expected font.

  user_pref("font.default.th", "sans-serif");
  user_pref("font.name.sans-serif.th", "Waree");
  user_pref("font.name.serif.th", "Kinnari");

Thanks.  That at least means that these preferences are being used, but leaves
the question of why they the recent code is not resolving these to the
expected fonts.  I suspect bug 390900 is also involved here (but not the whole
issue).

I think this should be fixed by a couple other fixes that I just landed to inbould.

Here's a trybuild to test with:

Please let me know whether this fixes your problem or not.
