I found that when I place an image (with ronder corners) in a container (with rounder corners), set the container overflow to hide and try to use hover animations to give the image a zoom effect, the enlarged image makes the rounder corners of the container disapear.
Before hover
after hover
this is an item in a repeater, i have set both the repeater items and container to overflow hidden & corners all 15 px rounded.
It would be helpfull if anybody has a workaround
