changeset comment: fix delete button issue issue: when deleting comments in a list of comments on the same line, sometimes the add new comment button stops working root cause: when deleting a comment in a list of comments that are all on the same line, the wrong previous tr is chosen, the chosen tr could be an inline comments instead of a line tr, resulting in the fact that injectinlineform function will return immediatly solution: loop over the found tr until its no longer an inline comment remark: could probably be optimised futher to immediatly search for the line tr object
