Harper breaks search on Discord website on Firefox

Describe the bug

When I type certain strings on the Discord web search, the website crashes halfway through inputting the string. E.g. it crashes at 'e' in "qwerty" and 'v' in "never", but it allows me to type "cat" and "dog".

1. Open the Discord website on Firefox
2. Try to type certain strings in the server search box.
3. Discord crashes, and the terminal message given in "Additional context" is displayed.

Expected behavior

Be able to type full words in the search box.

Platform

Firefox on Ubuntu 24.04

Additional context

The error given in the terminal is

Error: invariant(...): Second argument must be a string.
