Broken zoom out view when exiting style book

[ajlende]

Description

The zoomed out view is too narrow when exiting the style book.

I assume it's related to saving the initial width of a container that doesn't exist when entering zoom out.

Step-by-step reproduction instructions

1. Start in the site editor.
2. Open the 'Styles' sidebar.
3. Open the 'Style Book'.
4. Enter 'Zoom Out'.
5. Close the 'Style Book'.

I've also sometimes been able to reproduce the issue when entering zoom out via 'Browse Styles' and then opening the 'Style Book'.
