TinyMCE editor in Text widget does not have RTL contents

[sa3idho]

The visual editor of the text widget has alignment issue in RTL languages.

@azaozz is this an issue with wp.editor.initialize()?

[westonruter]

@sa3idho to confirm, it's the contents of the editor that actually aren't displaying in RTL when they should, correct?

[sa3idho]

@westonruter Yeah that's right, it's the contents of the visual editor that actually aren't displaying in RTL.

The solution is:

jQuery( document ).on( 'tinymce-editor-setup', function( event, editor ) {
    
    editor.settings.directionality = 'rtl';
 
});

@guytzhak please test 40972.0.diff​.

@azaozz is this the right approach?

[sa3idho]

Replying to westonruter: It is a right approach :-)

Replying to westonruter:

Yep, that should work. We don't set directionality: 'ltr' when outputting the settings for the other editor, maybe better to leave that out here too.
