"Thai text in some UI elements will be displayed overlapped on Windows

Anyone has an idea where should I start looking?
Looks like the problem here is the glyph fallback, given the four input
characters there are 4 glyph "slots". Under Linux even if we have
combining characters or zero-width glyphs then we get 4 glyph slots that
map back to 4 character slots so we can always associate a glyph slot to
a character even if no real glyph exists for that slot, so we fall out
early from a loop that intends to calculate where to place the fallback
glyph.
I attached a hackaround patch to the issue, does that "work" for you ?
