Red Heart Emoji Showing Up White

> Why is the red heart (\u2764\uFE0F) in Simplenote converted to the black one (\u2764)?
>
> If I use the shortcut “WINDOWS + .” the emoji panel opens and I can select the red heart (\u2764\uFE0F). If I do so it will be transformed to the simple white/black one (\u2764). If I input the red heart somewhere else first and copy it in it will stay like the original. The heart with the stars as comparison works fine both ways (as do also all other emojis in simplenote).
>
> Would it be possible to correct this behaviour, since the red heart is the only emoji that does not input as all the others? The black/white heart is sad to look at but then also bothersome to copy+paste the heart continuously. Thank you! :)

### Expected

Using the red heart emoji should look like the emoji and not change to a white emoji.

### Observed

The emoji can be copied and pasted to the correct red emoji. It cannot be selected from the emoji selection as it changes to white.

### Reproduced

1. Open app.simplenote.com
2. start a new note
3. use the shortcut to pull up the emoji options
4. select the normal red heart.
5. I should appear white in the body but in the side preview it shows the correct red heart

### Where did you see the bug

Chrome Browser Version 125.0 (on Windows 10): Simplenote Web Version

Start by reproducing the issue in app.simplenote.com using Chrome 125 on Windows 10, following the listed emoji-picker steps. Compare the editor body with the side preview for the red heart variation; done means selecting the red heart keeps it red in the note body as well as the preview.
