wp_check_filetype() returns false for html files

[onnimonni]

Is this intentional behaviour?

Running:

<?php
var_dump( wp_check_filetype( 'example.html' ) );

outputs:

array(2) {
  'ext' =>
  bool(false)
  'type' =>
  bool(false)
}

Hi @onnimonni. This is probably related to #39550.

Thanks to @joedolson for testing that this is no longer valid.

From Joe:
Yes, this is fixed. Now returns correct text/html info
