What is the problem?

In the "Insert link" dialog, if you interact with the radio buttons on Safari they no longer appear to be selected.

So far, it seems to be a visual bug. If you do click on a radio button, although it does not appear selected, the behaviour is correct.

For example, if you click "To an external webpage" it will insert an external link.

I wonder if it is not another symptom of this bug T301226.

Steps to reproduce problem

1. Start editing any page on Safari
2. Open the "Insert link" dialog
3. Click either of the radio buttons

Expected behavior: The radio button is changed as appropriate
Observed behavior: Both radio buttons appear unselected
