Hi, I'm going to fix a scrolling issue for RTL mode in Gecko, whose solution may depend on the behavior of scrollLeft. Thus I hope to confirm with the working group about the behavior first. It seems that, for scrolling within RTL or vertical-rl element/document, the behavior significantly varies across impls. I made a page to test the behavior, and also listed the result I saw there. [1] As shown in the table in that page, in all cases with RTL or vertical-rl, Gecko returns 0 for scrollLeft when the scrollbar stops at the rightmost, and returns negative values otherwise. It seems to me that this behavior matches what the CSSOM View spec says [2], but doesn't currently match any other impl. However, since I'm not quite familiar with that spec, and the wording looks obscure to me, if anyone can confirm that behavior, that would really help.
