Initial collapsed state is always false on the initial render

[ocimer]

Describe the bug
Initial state of the collapsed value is always false on the initial render (only), even when "defaultCollapsed" prop is set.

To Reproduce
Steps to reproduce the behavior:

1. Go to sanbox
2. Refresh the page in the web view area and observe the console and the web view area.
3. In the web view you will clearly see a jump from not collapsed to collapsed on page refresh, and the console will output "false" on initial render and "true" after.

Expected behavior
With the "defaultCollapsed" prop set I expect the sidebar to be collapsed even on the initial render.

Desktop (please complete the following information):
Any modern browser
