 Hello @pienoz, welcome to WordPress Trac!

 `ionic` is not part of the default list of supported protocols by
 [https://developer.wordpress.org/reference/functions/wp_allowed_protocols/
 wp_allowed_protocols()]. But you can easily extend the list with the help
 of the
 [https://developer.wordpress.org/reference/hooks/kses_allowed_protocols/
 kses_allowed_protocols] filter:

 {{{#!php
 <?php
 add_filter( 'kses_allowed_protocols', function( $protocols ) {
     $protocols[] = 'ionic';
     return $protocols;
 } );
 }}}

 With this snippet you can continue to use `ionic` in the Origin header.
