Issue Summary

This is reproducible on Data Center: yes

Steps to Reproduce

1. Close your Workspace menu
2. Open the Calendar Power-Up View on a board
3. Note the weekday alignment with the numbered dates
4. Open the side workspace menu

Expected Results

The weekdays align correctly regardless of the workspace menu being open and only leaving space for 6 days in the view, or with the menu closed and showing all 7 days of the week. 

Actual Results

The Calendar View will behave as if there were always 7 days and squish the weekdays together

Workaround

• Open the Calendar View with the Workspace Menu already open.
• Refresh the Page.
