Post Thumbnails: When using add_theme_support( ‘post-thumbnails’, array( $post_types) ) merge the supported post_types.

Browse Source 
Allow the adding of post-thumbnail support for one or more post_types without unsetting any previously added post_types. This matches the behavior of other uses of `add_theme_support()` and the expectations of a function with a prefix of “add”.
To unset post-thumbnail support use `remove_theme_support()` instead.

Fixes #22080
