Why doesn't Safari copy URL parameters of a link when using the 'copy' from menu?

I found a strange behaviour on Safari that seems to be affecting URL sharing. If I copy the url by selecting all coping it I can share the full link. Such as www.somesite.com/somepage?params=somename&urlparams=someothername When I copy paste a link by using "copy" from the menu, all the url params that are in the url are gone and I can only copy paste this: www.somesite.com/somepage Is there a bug on safari or some option that stops params from being shared? Currently this happens on: software version 15.4
