Sort of in the style of that old classic, ‘What goes through the green glass door?’

- Gel does, but official doesn’t.
- Chin does, but tongue doesn’t.
- Sticking does, but stuck doesn’t.
- Mistake does, but miss doesn’t.
- Nomad does, but rover doesn’t.
- Peeping does, but loom doesn’t.
- Tall does, but small doesn’t.

What gets past the bluegrass bulge?
Hint 1:
Each combination is attested at least twice, on both sides.
Hint 2:
There’s more linguistics involved than in the previous one.
Hint 3:
I didn’t count things that were part of affricate consonants.
Hint 4:
Vowel doesn’t get past, and that makes sense in 1 out of 3 cases. Vowels doesn’t either, but that makes sense in 2 out of 3 cases. Neither gets past for the same reason, though.
Hint 5:
You might say that part of the solution is the opposite of the original solution; there the IPA has nothing to do with it. The third referred to in the previous hint is the same. But the last third does.
