Improve the check for sourceless or dimensionless media when determining if the lazy loading attribute should be added to iframes and images. Never include the lazy loading attribute on embeds of WordPress posts as the iframe is initially hidden.
Including `loading="lazy"` on initially hidden iframes and images can prevent the media from loading in some browsers.

The reorganization of the PHPUnit workflow in [50441] unintentionally caused the tests to be run for every `push` event, even for forks and private mirrors.
Previously, the second job required the first one to pass, and the conditional check on the first prevented both from running. Because the first job is no longer required for the second, both jobs must have the appropriate conditional check.

In the wrapper function `wp_getimagesize()` check if the second parameter was passed before sending it to the PHP function `getimagesize()`.
The PHP function has a different execution path depending on the number of parameters passed, this ensures the wrapper function follows the appropriate path.

When validating `enum` values as `integer` or `number`, consider a number with a zero fractional part to be equivalent to an integer of the same value.
In `rest_are_values_equal()`, when comparing two values of type `int` or `float` (in any combination), first cast both of them to `float` and then compare.
This matches some test cases from the official JSON Schema test suite.

Because the changes in Twenty Twelve did not impact site look or functionality, version 3.4 of Twenty Twelve was not released in coordination with WordPress 5.7.
This reverts the portion of [50508] relevant to Twenty Twelve, changing the version back to 3.3 so that version 3.4 is not skipped accidentally when there are changes that should be released.

On TravisCI, old branches still receiving security updates were tested on a regular basis. This ensured tests continued to pass as time passed even if updates were not made to these branches.
On GitHub Actions, there is no interface to configure this (TravisCI had a UI), but there is a `schedule` event that can trigger workflow runs on cron that can be used to accomplish the same thing.
This introduces a workflow file that runs twice a month (on the 1st and 15th) to verify the tests within older branches.
Because the `schedule` event only runs within the primary branch, the appropriate workflows in each old branch will be triggered manually through the `workflow_dispatch` trigger using the GitHub REST API. `workflow_dispatch` will need to be added to all workflows in all old branches in order for the event to dispatch successfully.

The editor uses the full height of its container, so the added margins cause the visual editor to break out of the container. This removes the top & bottom margins, and makes the left & right margins consistent with the meta box area.

Removes the mutually exclusive directives check in `wp_robots()`, ie allow both `follow` and `nofollow` to be specified and for `archive` and `noarchive` to be specified.
This fixes a bug in which WordPress would defer to the most permissive over the least permissive. When contradictory instructions are included, WordPress will defer to the search engine's or archivist's resolution policy: generally this is to observe the least, not most permissive.
