I can get that image to open and occupy the entire expando width in /all, in the sub or in the post itself.
There must be something wrong with your browser (maybe a 3rd party extension blocking js).
When i started writing this comment it was still happening even when I turned off all extensions... but I think you fixed it on the fly as I was investigating for you... now that come up full width.
lol I did made a change that will improve the compatibility with all browsers and was about to ask you.
looks like you reintroduced the issues with pagination and scroll position though... that was working again this morning until this last change you made.
