Bug – widgets dashboard issue

Hello,

Thanks a lot for this simple but yet very powerful plugin.

Everything works fine with this plugin but I found a small bug on the plugin. There are some themes that use customize systems on their widgets dashboard to speed up the loading of the widget dashboard page that has many widgets on their theme. I will explain more clearly below.

[Plugin version 2.5.3]
in polylang/js/widgets.js on line 37, there is a condition that detects if the user on customizer or on the Widgets Dashboard. here the code :

...
if ( 'undefined' !== typeof wp.customize ) {
...

is it better if the condition also detects the page ?

Thank you
