[Bug] Trying to add a version description with emojis fails silently

[JhonnyTheJeccer]

When trying to add a version description with an emoji, the website fails silently and refuses to make the version.

OS: Pop!_OS 22.04
Browser: Firefox 108.0
Version Name: Test
Version Description: 🎉 (\U0001f389)
Zero-Width: no
Private: no
Image Upload: the same file that was used for the first version (.webm)
Behaviour: Button with submit is pressed, then nothing happens. Button can be pressed again without effect, each button press generates a new error message.
Error reported by console:

TypeError: XMLHttpRequest.setRequestHeader: Cannot convert argument 2 to ByteString because the character at index 95 has value 55356 which is greater than 255.
