Steps to reproduce

When changing the background color, cancelling, and changing the text color instead in document properties it changes the value for both fields.

1. Click Document Properties -> Design -> Chose Background Color
2. In the Background Color editor, select a color and then hit Cancel
3. Click on Chose for Text Color and make a selection
4. Click Ok to close out of the Document Properties dialog

Expected result

Actual result

Document background color AND text color are changed
