How to reproduce:

1. Enable the "Mark all edits minor by default" option in the preferences.
2. Edit a page in the VisualEditor.
3. Press "Review and save", then "Looks good to me".
4. The edit summary entering bubble appears.

Observed:

• The "This is a minor edit" box is not checked.

Expected:

• The "This is a minor edit" box is checked.

Comment: The saved revision IS correctly marked as minor. It's just the check box that appears incorrectly.

GWT scenario for Cucumber:
Given that I am editing an article while the minordefault preference is on
When I am saving the article
Then the "This is a minor edit" box is checked
