The link editor overwrites my mouse clipboard on Linux

When I open the link editor by clicking on the link button in the RTE, the dialog that appears immediately erases the entry in my clipboard (which is most likely the URL I'm linking to).

This happens because the dialog automatically highlights the "http://" text that appears in the input field. First of all, a text box seeded with "http://" will never help me. It's useless. I will erase is 100% of the time. And because it gets automatically selected, it overwrites my clipboard entry. Now I have to delete "http://", go find my URL again and reselect it, then I can paste it into the box.

Please remove the "http://" from this input box.
