How do you enable 'style_formats'?

If you add it as a property, then the value is wrapped in double quotes. This is wrong, since the value is a native JS array.

I figured out a workaround: edit the file /core/components/tinymce/templates/script.tpl

Right after:

Tiny.config = <?php echo $this->modx->toJSON($this->properties); ?>;

Add something like:

Tiny.config.style_formats = [ ...my javascript array values here...  ];

Or you can be a little tricky and add a property called style_formats and then correctly add it yourself:

<?php 
if($this->properties['style_formats']){
    echo 'Tiny.config.style_formats = ' . $this->properties['style_formats'] .';';  
}
?>

This is what I've done and it works, however be aware that the property is also included in the first line above.

I would actually suggest completely ditching modx->toJSON(), it's far too aggressive for what needs to be done with TinyMCE properties. A simple for loop echoing out the array as a JSON object literal would suffice. At least then you could do a quick check for control characters like [ or look at the key and leave off the quotes for things that require javascript array literals.
