Emojis added in Unicode 15 and 16 are not able to be selected

[ByteOfBrie]

Describe the bug

On Cinny web (tested on Firefox on Linux and on Windows), I cannot properly interact any of the new emojis added in Unicode 15 or Unicode 16.

For example:

(For my testing, I primarily used light_blue_heart (🩵) and compared it to blue_heart (💙), which is older and works properly)

If the light_blue_heart emoji is added to the top four most frequent of io.element.recent_emoji (which I edited the frequency of manually using Element and /devtools), the quick emoji picker will display less emojis:

For reference, this is how it should look:

Reproduction

1. Click on emoji picker
2. Search for an emoji added in Unicode 15 or 16 (ex: light_blue_heart)
3. It doesn't show up

Expected behavior

The emoji appears in the emoji picker and as a quick reaction

Platform and versions

1. OS: Linux, Windows
2. Firefox 133.0
3. Cinny version: v4.2.3 (app.cinny.in)
4. Matrix homeserver: self-hosted conduit

Additional context

Both emojis appear when sent as a message (and are fine if copy-pasted into the Cinny message input):

When emoji reactions are used in other clients, they render properly in Cinny:

When hovering over an emoji reaction, they do not appear consistent with other emojis:

other emojis:

It is apparently still possible to react with the emoji, but it cannot be selected:

1. Open the emoji picker
2. Paste the 🩵 emoji into the bar
3. Click react, the emoji appears properly
