Changes (by westonruter):

 * version:  4.4.2 => 3.9


Comment:

 The code for `buildWidgetSelectors` has been in place since 3.9.

 @martin.krcho could you please share the `register_sidebar()` calls that
 the theme has?

 You're right that a problem here is that `String.replace()` will only
 replace the first instance if the replacement arg is a string instead of a
 regular expression. So changing the pattern it to be a regular expression
 instead of string should do it, but I want to see how the sidebars are
 registered to see what is going on.
