Brackets in instance Name of wp_editor() breaks Tinymce

[3cees]

If I a pass an array name for an editor ID , the editor gets only shown as "teeny".

As described in the functions refrence:

textarea_name
(string) (optional) The name assigned to the generated textarea and passed parameter when the form is submitted. (may include [] to pass data as array)
Default: $editor_id

It should work.

Here an example:

$editor_id = 'my_options[op_'.$pool["slug"].']';
wp_editor( $content, $editor_id, array( "media_buttons" => FALSE, "textarea_rows" => 10, "teeny" => FALSE ) );
