[bug] Product page: clicking on a "color variation" thumbnails has no effect

[iawo]

Hello,

after upgrading Prestashop from 1.4.4.1 to 1.6.1.7,  a problem with color attributes appeared.

 

Previously, whenever clicking on a color thumbnail in the "choose a color variation" frame, the corresponding attribute value would be automatically selected in the dropdown list, and corresponding photos would appear.

 

After the upgrade, clicking on a "color variation" thumbnail has no effect.
