1. Type the text "Foo bar baz"
2. Select "bar"
3. Click the link toolbar button
4. Click between the a and the z ("ba|z") to cause the inspector to close
5. Press enter

Expected result: paragraph is split with "z" in a new paragraph
Actual result: "bar" is removed, paragraph is split with "baz" in a new paragraph

Occurs in both Firefox and Chrome. Isn't reproducible 100% of the time.

Theory:
1. User changes selection to ba|z
2. SurfaceObserver notices and adjusts its selection
3. Link inspector notices and triggers annotation on a fragment with a different range (the link)
4. Some bug in SurfaceObserver or SurfaceFragment causes SO to believe the current selection is now the link
5. User presses enter, SO removes what it believes is the selection
