Cannot associte ZWJ emoji with sticker

[laggykiller]

Using a supported version?

• I have searched searched open and closed issues for duplicates.
• I am using Signal-Desktop as provided by the Signal team, not a 3rd-party package.

Overall summary

We cannot associate ZWJ emoji with a sticker using Signal Desktop (e.g. 🙂‍↕️)

If I use signalstickers-client force upload a ZWJ emoji, only the first character of the ZWJ emoji is preserved (e.g. 🙂‍↕️ -> 🙂)

Steps to reproduce

1. Create sticker pack with Signal Desktop
2. Try to select emoji to associate with sticker
3. Note that ZWJ emoji could not be selected

Expected result

ZWJ emoji could be associated with sticker

Actual result

ZWJ emoji could not be associated with sticker

On a side note when looking at sticker improvements:
With unicode 16.0 we have things like "woman kneeling with semi-dark skin facing to the right". If I want to create a sticker which is suggested to any kneeling person emoji of any skin color and direction, a max limit of 13 emoji / unicode characters associated to one sticker doesn't cut it. Could that limit be raised quite a bit?
Edit: Was told the skin color is ignored anyway, yet still a higher limit would be helpful
