One of the recent updates broke WP_HTML_Tag_Processor's PHPUnit tests

[anton-vlasenko]

Description

I've noticed that these changes break PHPUnit tests on PHP 5.6:
https://github.com/WordPress/gutenberg/pull/46018/files#diff-93724b2f6e5dbf16c2b3c0efea57fa442b572f75f325d1cb185cf614b692cf9f
If I revert the changes made to the WP_HTML_Tag_Processor class in that PR, then PHPUnit tests pass.

Step-by-step reproduction instructions

1. Install docker.
2. Checkout Gutenberg; navigate to its directory.
3. Add this line to the .wp-env.json file:

"phpVersion": "5.6",

4. npm ci
5. npm run build
6. composer config platform.php 5.6
7. composer remove spatie/phpunit-watcher --dev --no-update
8. composer update
9. npm run wp-env start
10. npm run test:unit:php
11. Observe failed tests in the console.
