 I recently noticed several problems related to how the WordPress query
 loop is handled in block themes, which partially comes down to the core
 implementation itself, but also to incorrect usage in e.g. the default
 theme Twenty Twenty-Three.

 Concretely:
 * TT3 is not using the `core/query` and `core/post-template` blocks in its
 `page.html` and `single.html` template. While that may intuitively seem
 like the right thing to do since these templates only display a single
 post, it is not: It has always been a best practice to always go through
 the query loop (i.e. `while( have_posts() ) { the_post(); ... }`), classic
 themes have always been doing that - check e.g. TT1's `page.php` and
 `single.php` for reference.
 * Not going through the query loop leads to several problems as the loop
 is never started, which apparently were so far were partially addressed by
 workarounds in Gutenberg, e.g. automatically starting the loop when in the
 `core/post-content` block, or similarly later in the `core/post-featured-
 image` block. These are workarounds though that lead to other bugs like
 #58027.
 * Additionally, wherever TT3 uses the `core/query` block, it includes
 parameters that customize the query, which should not happen as those
 templates should simply use the global main query, similar to how the
 equivalent classic themes would do it. In other words, all usages of the
 `core/query` block should solely set `{"query":{"inherit": true}}` and no
 other "query"-specific parameters (layout parameters are okay of course).

 There are a few other related aspects that need to be fixed in core &
 Gutenberg directly, but as a starting point we need to use the
 `core/query` block correctly in TT3.
