bug(web): selecting ការ in predictive text then pressing space gives suggestions starting with ការ #16587
Description
For example:
- select ការ
- press spacebar
- predictions show words starting with ការ - which does not really seem right
- select ការងារ
- result is កាការងារ
Not really sure what intent is but deleting រ from first instance of ការ is definitely wrong.

See also #16585 (comment); I believe the underlying cause may be the same, as missing whitespace spans would likely be "invisible" in cached tokenized context, thus the start of a new word would alias to the end of the previous word.
That said, I think I did previously enhance the
khmer_angkormodel somewhat, so I should probably inspect a bit deeper. We'd definitely see this comment's noted affects formon_anonta, at the least.jahorton commentedon Sep 18, 2026
OK, I've confirmed that the
sil.km.gccmodel would be suspect to the same issues - it uses a similar, but enhanced, .split().jahorton commentedon Oct 27, 2026
Took me a while to get back to this; see the following:
I'm also working on a smaller-scale fix to address cases where a context-final empty token isn't properly emitted; that part is kinda simple to detect. Interestingly, there are some edge cases in our current wordbreakers where it's missing, so I should address those too.
