Block Context Not Always Passed down through template parts in the site editor

[tomjn]

Description

While trying to work around #49072 I placed a template part inside a post template block so that I could reuse a post template like this:

This works on the frontend, but it does not work in the site editor.

The resulting posts did not inherit block context and instead of a list of posts matching the query block, I saw a single post showing generic post placeholder blocks

Step-by-step reproduction instructions

Create a query block with post titles, etc, and then turn the descendants of the post template block into a template part ( but not the post template block itself, just its children )

Screenshots, screen recording, code snippet

This works on the frontend, but not in the site editor.

Here's an example to make things clearer:

Block context successfully passes down on the frontend, but not in the editor

I did some more testing and this appears to have magically solved itself, I'm a little confused, but now template parts inside post template blocks are displaying correctly in the site editor, happy days I guess?

Hi,
This issue has gone 30 days without any activity. This means it is time for a check-in to make sure it is still relevant. If you are still experiencing this issue with the latest versions, you can help the project by responding to confirm the problem and by providing any updated reproduction steps.
Thanks for helping out.

This is still a problem, and highly inconsistent.

For example, given this structure:

• query block
  • post template block
    • template part
      • featured image/title/etc

The blocks show the latest published post, even when the query block specifies a category that has a single post in it that is not the latest post.

The post template block shows the correct classes for the correct post, but blocks inside the template part generate markup for the incorrect post ( latest published post that does not match query block ).

Note that the site editor shows the correct post, which is proving incredibly confusing for the client.
