"Enable full-height editor" setting only saved on page refresh

[GunGeekATX]

Testing the "Enable full-height editor and distraction-free functionality." setting on my personal site as well as a customer's site:

• logged in: setting is enabled (Add New Post, Screen Options)
• disable and logout immediately (without changing anything or refreshing page)
• logged back in: still enabled
• disable, refresh page and then logout
• logged back in: now disabled
• enable and logout immediately
• logged back in: still disabled
• enable, refreshed page and logged out
• logged back in: now enabled

I also verified this using wp user meta get 1 rug3dk50q_user-settings while performing the same actions. Watching the Chrome network tab, it appears that clicking the checkbox for this setting is not triggering an admin-ajax call to update this user setting, whereas the Boxes and Layout screen options do trigger the call.

It does appear to correctly update the wp-settings-1 cookie correctly when the setting is toggled.
