Chromium Native Memory Profiler shows 5MB in Page.Image for about:blank Page.Image 5 425 KiB 27.9% That's of a 19MB total. I'm not sure if that number is accurate or not, but it seems we have a problem either way. :)

How large is the browser window you have? I would expect that during rendering, it keeps around an image of width x height x 2 bytes

Changing the size of the window and snapshotting again does not seem to change this number. I've tried with large and small windows, and they get 5MB pretty consistently. My display is 2560 x 1600 and the window was at least 2/3 the size of the screen. Suggesting that if the backing-store was counted, we should be seeing more like 10MB of storage, no?

I suspect it may also be 5MB of images loaded to run the inspector?

It could be canvas image used by InspectorOverlay https://bugs.webkit.org/show_bug.cgi?id=99429 Unfortunately we can't count this image as a part of Inspector block because we are not able to track the ownership of an object at the moment but we are working in this direction.
