 This is a follow-up to #12009.

 While adding support for registering a script with an 'async' or 'defer'
 loading strategy, the solution that was committed [56033] did not include
 support for scripts that have an inline script attached in the 'after'
 position, nor if any script that is a dependent of the script has an
 inline script attached in the after position. In either scenario, the
 original script will be printed without the registered loading strategy in
 order to maintain execution order of the scripts in the dependency chain
 when an inline script is included.

 The purpose of this ticket is to reopen discussion about adding support
 for this use case. An initial implementation that included support for
 this use case was included in [https://github.com/WordPress/wordpress-
 develop/pull/4391/ the initial PR] prior to removal in
 [https://github.com/WordPress/wordpress-
 develop/pull/4391/commits/b7d362df9655eedd2aff8651addd497fca83f1d0 this
 commit]. Relevant conversation on the initial ticket that led to the
 decision to remove support for inline scripts starts at
