Message:

Script Loader: Use wp_get_script_tag() and wp_get_inline_script_tag()/wp_print_inline_script_tag() helper functions to output scripts on the frontend and login screen.

Using script tag helper functions allows plugins to employ the wp_script_attributes and wp_inline_script_attributes filters to inject the nonce attribute to apply Content Security Policy (e.g. Strict CSP). Use of helper functions also simplifies logic in WP_Scripts.

• Update wp_get_inline_script_tag() to wrap inline script in CDATA blocks for XHTML-compatibility when not using HTML5.
• Ensure the type attribute is printed first in wp_get_inline_script_tag() for back-compat.
• Wrap existing <script> tags in output buffering to retain IDE supports.
• In wp_get_inline_script_tag(), append the newline to $javascript before it is passed into the wp_inline_script_attributes filter so that the CSP hash can be computed properly.
• In the_block_template_skip_link(), opt to enqueue the inline script rather than print it.
• Add ext-php to composer.json under suggest as previously it was an undeclared dependency for running PHPUnit tests.
• Update tests to rely on DOMDocument to compare script markup, normalizing unsemantic differences.
