 I'm attaching here a patch I also attached on #28580, and as I
 [https://core.trac.wordpress.org/ticket/28580#comment:17 commented], in
 [attachment:31793.diff] the `ThemeControl`'s `renderContent` method gets
 deferred until the containing section is expanded, meaning that the
 screenshots won't load until the Theme Switcher panel is opened. Given the
 lateness of the release cycle, I think such a Theme Switcher-specific
 loading optimization should be what is in scope. /cc @mattwiebe
