Comment (by SergeyBiryukov):

 In [changeset:"43040" 43040]:
 {{{
 #!CommitTicketReference repository="" revision="43040"
 Themes: Avoid a PHP 7.2 warning in `get_theme_roots()` when
 `$wp_theme_directories` is an uncountable value.

 See [41174] for `wp_get_themes()` and `get_raw_theme_root()`.

 Props burlingtonbytes, teddytime, lbenicio, desrosj.
 Merges [43039] to the 4.9 branch.
 Fixes #43374. See #40109.
