Pasting multi-codepoint glyph breaks it into two

Hi all,
When I paste a multi-codepoint glyph (or insert it via an input method), it
gets broken up into multiple glyphs.
Here is a reproduction example. To execute these, you need to ensure proper
unicode support on your terminal (I'm using foot).
Executing the following properly prints a pirate flag emoji (🏴☠):
printf "\U1f3f4\u200d\u2620\n"
But if I copy-paste that same glyph into my shell, I get:
🏴<200d>☠
However, if I run `cat -`, and paste the same value, cat properly prints back
the multi-codepoint glyph (the pirate flag in this case).
This happens only for some distinct emoji. E.g.: "man shrugging": 🤷♂️.
I have ruled out terminal support too (e.g.: as in the above example using
`cat`). I also cannot reproduce the issue when using bash on the same setup.
Have I stumbled upon a bug?
