Some of emojis are rendered correctly while typing but then incorrectly when displaying history.

Describe the bug
Scottish flag emoji is displayed as black flag after executing a command.
You're doing the great job btw so far, in all other terminals I tried cursor jumps all over the place when you paste an emoji like that in the prompt, warp allows you to type it properly.
To Reproduce
Type
printf '🏴' | wc -m
Notice that the flag is rendered correctly. Press enter.
Expected behaviour
The terminal displays printf '🏴' | wc -m followed by number of bytes in the grapheme.

Probably this will also help, this:
printf '👍🏾' | wc -m
is rendered as this in the history:
printf '👍 🏾' | wc -m but without the space, I had to remove the space so browser doesn't render the grapheme as single glyph.
echo '->'
Using -> provides another example. I have changed the font to one that supports ligatures (should render roughly as →). When typing, I see the ligature (the real arrow). But on enter, the history shows the - and >.
It seems Warp DOES NOT render history with the chosen font. Why not?
When I copy/paste the history into my IDE (or other application), I see emojis and ligatures correctly again.
For the Warp devs, to build on top of @tnymlr’s example, it seems to be an issue with any multi-code-point character.
echo '🌤 🏴'
| Typed | Rendered |
|---|---|

You can see the code points on Emojipedia: Sun Behind Cloud (1 code point) and Flag for Scotland (7 code points).
The Flag for Scotland seems like a great test case given it represents a tag sequence.
