	 * Most block themes omit the `core/query` and `core/post-template` blocks in their singular content templates.
	 * While this technically still works since singular content templates are always for only one post, it results in
	 * the main query loop never being entered which causes bugs in core and the plugin ecosystem.
	 *
	 * The workaround below ensures that the loop is started even for those singular templates. The while loop will by
	 * definition only go through a single iteration, i.e. `do_blocks()` is only called once. Additional safeguard
	 * checks are included to ensure the main query loop has not been tampered with and really only encompasses a
	 * single post.
	 *
	 * Even if the block template contained a `core/query` and `core/post-template` block referencing the main query
	 * loop, it would not cause errors since it would use a cloned instance and go through the same loop of a single
	 * post, within the actual main query loop.
	 *
	 * This special logic should be skipped if the current template does not come from the current theme, in which case
	 * it has been injected by a plugin by hijacking the block template loader mechanism. In that case, entirely custom
	 * logic may be applied which is unpredictable and therefore safer to omit this special handling on.
