Comment (by westonruter):

 It also works well in my testing. I tried throwing every possible image
 into the content, from floats to inlines to full-bleeds, including both
 image blocks and classic block.

 To help test I also created a test plugin to slow down the images in the
 content:

 Adding the width/height makes a huge difference with this plugin. Without
 the width/height insertion, there is a bunch of content shifting. But when
 the width/height are in place, the layout is stable.
