"Current Color" string is ignored ( wpColorPickerL10n.current ). Data attribute is missing.

To fix this issue replace :

self.toggler = $( _before ).insertBefore( el ).css( { backgroundColor : self.initialValue } ).attr( 'title', wpColorPickerL10n.pick ).data( 'current', wpColorPickerL10n.current );

with:

self.toggler = $( _before ).insertBefore( el ).css( { backgroundColor: self.initialValue } ).attr( 'title', wpColorPickerL10n.pick ).attr( 'data-current', wpColorPickerL10n.current );
