Bad javascript send multiple Ajax request on widgets administration page

Plugin version 5.0.11
In the following file “src/widget/js/widget.js” at line 157,the selector is not precise enough :

$("input[name='savewidget']").click();

It trigger click event on all widgets save button and send as many ajax request as widgets …

It should be something like:
$(this).parents('.widget').find("[name='savewidget']").click();
