When bookmarking the page and copying the bookmark from the Library, we get a "nice" html link as text/html in the clipboard. When copying from the location bar, we only get the "ugly" url as text/plain. See example below.
-> Pasting into Teams etc. yields a "nice" link if copied from bookmarks (rare) but a "ugly" one if copied from location bar (standard case).
Linux, Firefox 102.0.
Functionally, the same is true in Windows. Note that Edge copies "nice" links from the location bar.
Example:
[user@host ~]$ # bookmark page and copy from Library
[user@host ~]$ xclip -selection clipboard -o -t TARGETS
