Affixing the link to the comment can definitely be improved. Though I’m not sure I exactly understand it not affixing to the correct letters. It should affix to the selection?

Previously, if the text with the link attached was too long, the last few letters of the text would not have the link attached. I’m not able to replicate this issue anymore so it might have gotten fixed.

However, if I add text with a link attached and press OK in the pop up box, and then afterwards type text that I do not want the link to be attached to, all text that follows has the link attached.
