In PR #45776 I added support to highlight the code that corresponds to the underline span for any given diagnostic in order to side step issue #42112.
I would like to receive as much feedback as possible on wether we should move forward with merging this change or not. Please feel free to go to the PR and leave a +1 or -1 reaction to it in order to gauge the mood of the community, as well as leaving comments both here and in the PR.
