I’m not sure it is a bug, to me, it is because this behavior is counter to what I expect to happen.

When I click where the X is marked, the cursor goes to the beginning instead of the end of the text (clicking more than once, doesn’t change anything). This happens with external links only.
It’s kind of annoying when there’s no content below the link because to continue writing I can’t just press enter for a new line. I need to press “End” for the cursor to go to the end of the line, and then “Enter” for a new line.
