I think I know why this is happening. I made the previous change to add support for proper whitespace prepending, but I don't think I took into account the case where the text is indented by the formatter (my patch worked by looking at the existing whitespace before the first property and applied that space to every other line). It is possible that the code I added doesn't take into account extra indentations not visible in the text of the style (like a formatted indent). As a fix, I think it may be necessary to look at the ownerRule and see how many items are in mediaList and indent that many times (similar to what generateCSSRuleString does in CSSStyleDeclaration.js).

Yeah, the old code tried to infer the base indent for the rule and applied it after editing.
