 Hi

 I've tried the following in WP 6.0 and 6.1 as well as the TwentyTwentyTwo
 and TwentyTwentyThree themes.

 Issue:
 When using the "Default Template" option on a Page, the page.php file is
 ignored but page.html will work. You will see in admin that it is set to
 Index as it is ignoring the page.php file but if you have both .html and
 .php the .html will take precedence.

 Admin + File structure:
 https://monosnap.com/file/0IwMr0nBwtXDkd8SEIb0QjUGTn7Qsb

 It looks like the problem comes from the code below in this file `wp-
 includes/block-template-utils.php` line 313

 {{{
     $template_slug      = substr(
     $template_file,
     // Starting position of slug.
     strpos( $template_file, $template_base_path . DIRECTORY_SEPARATOR ) +
 1 + strlen( $template_base_path ),
     // Subtract ending '.html'.
     -5
 );
 }}}

 I'm not certain but I also found this in the Gutenberg side and wondering
 if it didn't make it across (unless I'm mistaken).

 It's been driving me mad!
