Compare view: EOL character not shown by default in left pane

[Otiel]

Steps to reproduce

1. Set "code-eol.toggleWithWhiteSpace": true (or don't set it, because it is true by default).
2. Open a file.
3. Make sure whitespaces are shown (call "View: Toggle Render Whitespace" if needed)
4. Call the command "File: Compare Active File With..."
5. Select another file.

Actual results

• The left pane shows whitepaces, but no EOL character.
• The right pane correctly shows EOL characters with whitespaces.

Expected results

• EOL characters should be displayed in both panes.

Extra steps

6. Set focus on the left pane. EOL characters are now displayed!

Thanks for posting a video of it that is super helpful!

Right now the line endings get drawn because they're listening to a event like "document is active" or "edit document". I probably need to find another event for when the document is visible but not necessarily active. I'll start looking for that event, and once it's found this should be a 3 line fix.
