Porfolio grid on Safari browsers

Hi,
issue only on Safari (old, new, win, mac, ..all ):

rows with products are retracted each to other similar to fish scales. Blocks “grid-entry” are pushed by inline style of JS with position:absolute and top+left calculated positioning. On safari browsers is “top” value incorrect, maybe around half of correct value intended. This weird issue is visible mostly on Safari browser width from 768px up. and after any change of view (width of browser, zoom, etc.) it repairs itself.
In my case solution was:

/* fix for safari browsers */
@media (min-width:768px) {
	.h-portfolio .grid-entry {
		position:relative !important;
		top:auto !important;
		left:auto !important;
	}
}

with no impact on other browsers.
