 It seems that the link inserter breaks the TinyMCE style formats.
 P-tag is working, the link-tag not.

 {{{#!php
 <?php
 // Custom styles
 add_filter( 'mce_buttons_2', function( $buttons ){
     array_unshift( $buttons, 'styleselect' );
     return $buttons;
 } );
 add_filter( 'tiny_mce_before_init', function($init_array){
     $style_formats = [
         // These are the custom styles
         [
             'title' => 'Button',
             'inline' => 'a',
             'classes' => 'btn',
         ],
         [
             'title' => 'P',
             'block' => 'p',
             'classes' => 'largerp',
         ],
     ];
     // Insert the array, JSON ENCODED, into 'style_formats'
     $init_array['style_formats'] = json_encode( $style_formats );
     return $init_array;
 } );
 }}}
