Issue 870600  has been merged into this issue.

Able to reproduce the issue on Mac 10.13.3, Win-10 and Ubuntu 17.104 using chrome reported version #68.0.3440.84 and latest canary #70.0.3515.0.
This is a non-regression issue as it is observed from M60 old builds. 

Hence, marking it as untriaged to get more inputs from dev team.

Thanks...!!

This appears to be a layout issue, or maybe style resolution. The computed height of the image is 0px. It's specified as 100% but no parent element has 0 height. Forcing re-layout seems to fix it in that docking Devtools causes the height to compute and the image to appear, as does disabling the height: 100%; CSS rule on the image.

Looks like an invalidation problem, the image takes awhile to load and once it is loaded it never updates the height of the element. Interesting.

Looks like the culprit is |image_size_is_constrained| in LayoutImage::InvalidatePaintAndMarkForLayoutIfNeeded - it's not strict enough in this case and thus not triggering a layout when the image dimensions arrive.

Refactor "needs layout" check in LayoutImage

Move the conditions used to check if layout is needed when the intrinsic
size changes out into a new function, and call that from
LayoutImage::InvalidatePaintAndMarkForLayoutIfNeeded.
Replace open-coded HasRelativeLogicalWidth() with a call to that method.

Narrow "is constrained" check for LayoutImage layout invalidation

If our containing block has auto height, we need to relayout.
Add !HasAutoHeightOrContainingBlockWithAutoHeight() to the
condition for |image_size_is_constrained|.
