<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Script Loader: Add a temporary `jquery-migrate-compat-5.5` script handle.
This is intended as an easy way for plugins and themes to still be able to load jQuery with jQuery Migrate in WordPress 5.5.
Once jQuery is updated to 3.x, this temporary script handle will be removed. This means plugins and themes still using it at that point will fail to load their scripts (as a dependency will be missing), but will not cause "fatal errors" breaking the rest of JS.
