$version is not defined in editor_js() for TinyMCE

[littler.chicken]

Whenever I open an admin screen with a post edit field, I get this notice:

PHP Notice: Undefined variable: version in ...class-wp-editor.php on line 1426

It appears that $version has not been defined for the TinyMCE script in the editor_js() method. It looks like other methods in this class call the global and then use it to define the version, something like:

global $tinymce_version;
$version = 'ver=' . $tinymce_version;

If I add these two lines to the method, the notice is fixed. I know that the TinyMCE component was updated just this week but didn't see a ticket on this variable.
