Selection is not cleared when I have multiple CodeEditors and focus on a different one

[evanrolfe]

Describe the bug
If I have 2 or more CodeEditors in an app, and I make a text selection on CodeEditor #1, then focus on CodeEditor #2, the selection in the first CodeEditor remains.

To Reproduce
Steps to reproduce the behavior:

1. Have an app with 2 or more CodeEditors
2. Type text in both CodeEditors
3. Make a text selection on CodeEditor docs: fix pub link #1
4. Focus on CodeEditor slow highlight performance #2

Expected behavior
The selection from CodeEditor #1 should be cleared when any other CodeEditor is focused.

I think you use the same controller in two editors.
