Mismatch between header useragent and navigator.userAgent

My Torbrowser on Linux has the http-header-useragent: Mozilla/5.0 (Windows NT 10.0; rv:102.0) Gecko/20100101 Firefox/102.0, but the navigator.userAgent returns Mozilla/5.0 (X11; Linux x86_64; rv:102.0) Gecko/20100101 Firefox/102.0. This can be tested with https://coveryourtracks.eff.org/, Headers -> Useragent vs Hardware Specs -> Platform.

Having multiple values (Windows/Linux) here increases the possibility of being tracked. In my opinion, showing Windows as platform everywhere has the lowest tracking possibility.
