In [changeset:"61415" 61415]:
{{{
#!CommitTicketReference repository="" revision="61415"
Scripts: Remove non-HTML5 script support.
Remove the following behaviors that are obsolete in HTML5:
- CDATA wrappers around `SCRIPT` tag contents.
- Conversion of boolean attributes to strings (attribute `async="async"`
becomes `async`).
HTML5 was released in 2008 and data suggests virtually all WordPress sites
are served as HTML5. See #59883 for more details.
Developed in https://github.com/WordPress/wordpress-develop/pull/10660.
Props jonsurrell, westonruter, azaozz, soyebsalar01, dmsnell.
Fixes #64442. See #59883.
