In which case TNP gave you the best answer, and you should have known

I didn't know it was possible to do that.

supported in all major browsers since 2024 (Baseline 2024).

Details at MDN, as usual:
<https://developer.mozilla.org/en-US/docs/Web/URI/Reference/Fragment/Text_fragments>.

Note the options to include prefix and suffix parts to be matched, but
not highlighted.

In Chrome or Edge, select the required text, right click
then "copy link to highlight"
