Can't move cursor up and down after adding a link

[ghost]

In the demo I can add some links. When I enter a bunch of text, I can use my arrow keys to move the cursor up and down. Now when I add a link, the link is selected. When I click somewhere on the text and try to move the cursor up and down it won't succeed. Left and right is possible.

Now when I blur and regain focus it works as expected.

This looks like the same issue as #985.
