When you select some text on the paragraph block and press the Links button to add a link, the Links UI appears. If you dismiss it without adding any text to the URL filed, it will create a link with the url: http:\\

As a proposal: We shouldn't create a link if the url text is empty, but it should cancel the add-link action.

And (from @iamthomasbishop) we should consider a couple things:

• Tapping return should probably dismiss the sheet altogether. Right now, it just hides the keyboard. If we do this, we should probably rename this ^^ button to done.

• We should make sure the text input for URL use the URL input type/keyboard.

• (Maybe for another ticket): We are automatically adding http:// to URLs when the user types a straight URL. If I type wordpress.org, I would expect it to stay as wordpress.org.
