DateChooser with percentage width may display less than 7 columns

A DateChooser with a percentage width (but still large enough to display 7 columns) may display less than columns which is confusing as the dates no longer match the correct day.

Code to reproduce (will depend on your screen size):

```

```

Screen shot on Chrome


Start by running the supplied Royale ASJS XML reproduction and inspect the DateChooser component and its layout behavior at percentage width. Confirm the seven-column case at different screen sizes; done means a sufficiently wide DateChooser consistently displays all seven columns with dates aligned to their correct days.
