repost to make easier to read bug report// there maybe an issue already opened about this since, i checked the wrong issue list :D

Bug:

when there multiple comments on selection in the same line, it isn't possible to select which comment to interact with, whether to accept change or respond

To Reproduce
Steps to reproduce the behavior:

1 create a pad
2 make two comments on selection in the same line of any text
3 if you you try to go and accept the change/ try to select on of them (maybe as a different user)
4 you'll see that either they overlaps, in which case you need to get rid of the first one, or one of them doesn't get displayed

Expected behavior
to be able to access comments on selection on the right side of the text;
to show all comments if there are more then comments on selection
easy selection of which comment to interact
