If variant is sold out, there is huge cross displayed near the sold out variant but the cross is misplaced, so it is not clear which of the variants is actually out of stock.
This issue appears both on mobile and desktop.
SCR_01 = cross appearance when no variant is selected (product page)
SCR_02 = cross appearance when variants is selected (the first variant in the picture) – when selected, cross gets smaller
SCR_03 = cross appearance on product quick view
Please check whether something can be done, so the crosses are only on the right place (on the sold out variant) ands is in some reasonable size.
