Current Behavior

Certain images are not loading. I don't know yet what could be affecting it.

Figure not loading:

Possible Solution

Use threshold 0.0 (default)

Context

Loading a list, each element with a "profile" picture. So they have the same structure.
Chrome works OK Version 80.0.3987.149 (Official Build) (64-bit)

Config:

const observer = lozad('.lozad', {
  rootMargin: '200px 0px',
  threshold: 0.1
});
observer.observe();

Tested on:

• Browser Name and version: Firefox Developer Edition, 75.0b5 (64-bit), Chrome works OK Version 80.0.3987.149 (Official Build) (64-bit)
• Operating System and version (desktop or mobile): Ubuntu 20.04 Desktop

I had a similar issue with firefox/chrome and alt tag. I added to the lazy images following css: display:block;min-width:1px;min-height:1px; and that fixed the issue for me. Maybe that will fix the issue.
