Horizontal scroll on product page

[meswitch]

Horizontal scroll on product page appears when page width is 1200 px and lower.
Don't know what's causing it. Outling every element didn't help either.

I can't reproduce this on clean installation of niara theme. Most likely some module html/css.

Found it. It can be reproduced if a product has attributes (I use radio buttons), even one radio button element will have strange width like 682 px. The more attributes the longer horizontal scroll.
In product.css
.attribute_list input.attribute_radio {
width: 100%;
}
if turned off in inspector, horizontal scroll fully dissappears .
