Background image is not included into the list of items to test

[sergeychernyshev]

I tried to run 'descend' version on a page with background image on tag and it was not on the list. Tried both background attribute and background-image css property.

Can't think of a reason for it without knowing how asset list is created.

I can add code to get the background image tested if it's in the body tag, but parsing the CSS isn't likely to happen soon.

An alternative might be to use some HAR generator based on real browser to get a list of items on the page.

Wasn't a big deal for me anyway - can survive without it, but background images (along with CSS sprites) are quite popular technique.
