Chromium version isn't reduced in user-agent string

Since Chromium 101, Google Chrome only shows the major version in its User-Agent string: https://www.chromium.org/updates/ua-reduction/, e.g.:

Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/131.0.0.0 Safari/537.36

However, QtWebEngine still uses the full Chromium version number:

Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) QtWebEngine/6.8.1 Chrome/122.0.6261.171 Safari/537.36

Not only is that a privacy concern via fingerprinting (one of the original motivations for the change), but more importantly, it seems to break websites: Accessing https://www.sciencedirect.com/ with the default UA displays "There was a problem providing the content you requested". (Yes, the web is broken in fun ways sometimes...)
