In my case it was changing
img height from 100% to none (auto) but keep width 100%. I have to mention that I have set on these images
object-fit in custom CSS. I need to go back to it later to see a new Safari specifications. I found also next issue as I have set custom
list-style-type: "\2014 ";
that is also ignored with new Safari version and showing only standard dot. I thing there are coming a new rules for accepted HTML entities forms but didn’t have time to read about that. Like I’ve said when will be time I need to look into Safari Specs to see what is going on.
