Make copy/paste work for source code (#12191)
* Make copy/paste work for source code Fix regression casued by #12047 so copy/paste works properly in all browsers. Fixes #12184 Also while looking at this I saw a small display issue for blame view. I think #12023 was merged into original PR through an update branch before #12047 was merged and made one of the css ruules not apply anymore. * use pseudo-element to prevent copying of comment + symbol even when not visually selected * remove added newline here should not be necessary anymore * make sure empty line is newline so there is something to select and copy
