Reproduce steps:

1. Start a write any message.
   
2. Activate source mode (ctrl+shift+s)
   
3. Click 'Insert a link' button
   
4. Cancel the first pop-up and in a second pop-up you will see 'null' written in it.
   

Also when it creates another pop-up when you close one, browsers take it as spamming and adds "Prevent this page from creating another" checkbox.

I can reproduce this issue. When the first pop up comes up you have to press cancel and then it says null in the second one.

It is probably related to SCeditor... am I right?
