Description

Fixes #30565 and bobbingwide/fizzie#58

The problem was that there was no break in the loop, so .html templates with a higher specificity than .php templates were not properly detected.

This makes me wonder whether the logic to get the right template should be "merged" between block templates and php templates.

In other words instead of looping through the templates for php and then for html do it once and return the higher priority one starting with html.

Anyway such refactor could be considered separately.

This makes me wonder whether the logic to get the right template should be "merged" between block templates and php templates.

This makes me wonder what the Site Editor is supposed to do when it finds a .php template.

The block template resolution algorithm is quite complex, as it has to cover quite a lot of different possible cases resulting from various combinations of
- WP's "old" template hierarchy (including custom page templates, and child themes)
- block templates.

Things become especially complex when there are e.g. "oldschool" PHP templates with higher specificity than the available block templates; or when a child theme has a PHP template with equal specificity as the parent theme's corresponding block template.

For more discussion on this, see #31399. Examples of previous iterations that sought to refine the algorithms' behavior include #29026, #30599, #31123, and #31336. This PR's goal is to eventually cover all of those cases.
