Comment (by Bernhard Reiter):

 In [changeset:"56578" 56578]:
 {{{
 #!CommitTicketReference repository="" revision="56578"
 Themes: Inject `theme` attribute during serialization.

 Rather than using `_inject_theme_attribute_in_block_template_content` to
 inject the `theme` attribute into all Template Part blocks found in a
 given file-based Block Template, introduce a new function called
 `_inject_theme_attribute_in_template_part_block`, and use that as second
 argument to `serialize_blocks()` (introduced in [56557]) in order to
 inject said attribute during tree traversal for serialization.

 This allows for a more modular approach that will eventually be extended
 to implement automatic insertion of hooked blocks.

 Note that we're guarding `_build_block_template_result_from_file()` (i.e.
 the callsite of `_inject_theme_attribute_in_template_part_block` and
 previously of `_inject_theme_attribute_in_block_template_content`) against
 regressions through additional unit test coverage added in [56562].

 Props @gziolo.
 Fixes #59338. See #59313.
