 As originally reported as part of
 https://core.trac.wordpress.org/ticket/59633#comment:7: Certain data from
 block theme files is being cached (either via object cache or transient,
 in different use-cases).

 Any of these caches should be programmatically invalidated when editing
 the theme via the built-in Theme File Editor.

 While for regular theme development the `WP_DEVELOPMENT_MODE` constant
 (with a value of "theme") should be used, it is not reasonable to expect
 end users of WordPress that exclusively make use of the Theme File Editor
 to know about that.

 Whenever files of a theme are being edited via the Theme File Editor, any
 of these caches (introduced between WordPress 6.2 and 6.4 so far) should
 be invalidated / cleared.
