<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Themes: Block template is located twice in `get_query_template()`.
When the function `_template_loader_filters` was ported to core from gutenberg, it retained the filter to load block templates. However, the function `locate_block_template` is called manually in `get_query_template`, so this filter is not needed. Calling `locate_block_template` twice, results in performance issue, as `locate_block_template` is a expensive function to run, as it does database and file lookups.
