Spacing issue with masonry (mobile specific)

Hi Anders,

A few months ago I asked you about a spacing issue with the masonry. You advised to turn off lazyloading in Jetpack which fixed the problem on desktop: https://www.ads-software.com/support/topic/spacing-issue-with-masonry/

I noticed that the spacing issue continues to occur on mobile (Android) after scrolling past the first few posts, even if “view desktop site” is enabled. I wonder what is causing the different behaviour on mobile?
