Zoom out persists after reloads but not entirely engaged

[stokesman]

Description

If the page is reloaded while zoom out is engaged the mode is engaged upon reload yet the toolbar button is not shown as pressed and the view scaling/frame spacing is not present.

I'm not sure when/how this came about or if it was intentional.

Step-by-step reproduction instructions

1. Engage zoom out
2. Reload the page
3. Note that zoom out is still engaged (select a block and note the inserter buttons)

Encountered this as well, this is an important one to fix.

From my testing, this doesn't happen in the wp/6.7 branch, so I'm removing it from the WordPress 6.7 Editor Tasks board.

I believe #65945 introduced the persistence of the modes, and it wasn't backported for 6.7.

A fix will still be needed for trunk.
