Does not set previous selected item on focus

[efreibe]

When the control gains focus, it always select the first item in the list, despite of which option was selected at first.
Even when you select another option, if you go back to correct a mistake, you'll need to start searching all over again.
This could be a disadvantage when you are dealing with long lists.

I see that this is a duplicate of

#104

I've resolved this adding this lines:
Where it says:

$active = $dropdown_content.find("[data-selectable]").first();

I've added

$active = $dropdown_content.find("[data-selectable].selected");
if (!$active.length) $active = $dropdown_content.find("[data-selectable]").first(); }

I am experiencing the same issue. The code above fixes it. Thanks!
