Cannot type on Google docs with a custom user agent on firefox

[Quarta-feira]

I found out that when using an useragent on googledocs I cannot type or edit text. I use the extension on Firefox 121.0.1, 64bit, win11.
I tried out on blacklisted mode using the default Chrome Windows 118.0.0.0 or using my custom mode settings.
I can only type if I add docs.google.com on the 'Disable Spoofing' list.

How to replicate the bug:

Access docs.google.com, create a document and trying to type using one of the following extension settings

Blacklisted mode using the default Chrome Windows 118.0.0.0
Or
Using my custom mode settings:

{
  "google.com, youtube.com, bard.google.com": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/118.0.0.0 Safari/537.36",
  "bing.com, copilot.microsoft.com, xbox.com": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/114.0.0.0 Safari/537.36 Edg/114.0.1788.0"
}
