Description Simon Fraser (smfr) 2011-03-07 11:45:35 PST 
URL shows a testcase where you can't scroll to reveal left overflow on RTL pages.
Comment 1 mitz 2011-03-07 12:05:06 PST 
Huh? <html style="direction:ltr">.
Comment 2 mitz 2011-03-07 12:05:54 PST 
Meaning, that is not a right-to-left page (direction doesn’t propagate from <body> if it’s explicitly set on <html>).
Comment 3 Simon Fraser (smfr) 2011-03-07 12:15:57 PST 
Updated URL.
Comment 4 Simon Fraser (smfr) 2011-03-07 12:16:59 PST 
Caused by bug 55077?
Comment 5 mitz 2011-03-07 12:23:32 PST 
Simon, the updated URL still has <html style="direction:ltr;">.
Comment 6 Simon Fraser (smfr) 2011-03-07 12:40:50 PST 
Fixed.
Comment 7 mitz 2011-03-07 12:46:19 PST 
Does seem like a duplicate of bug 55077.
Comment 8 Yair Yogev 2011-03-07 23:39:15 PST 
i don't know which is correct but using the old URL (with <html style="direction:ltr"> but RTL body), FF showed a horizontal scrollbar while WebKit did not.

The direction propagation in Webkit (when dir is set in root) is different from that in Firefox.

In Webkit "Direction and writing-mode should propagate from the <body> to the <html> to the ICB as long as the <html> hasn't explicitly set the direction or writing-mode." (from dhyatt),

while Firefox always propagate the direction from the <body> to the initial containing block even if the <html> has explicitly set the direction.

Please refer to description and comment #9 in bug 48157.

In this bug, we didn't even get a scrollbar.

Using chrome linux, I see the same: horizontal scrollbar presents. but scroll does not reveal left overflow before r80622, and it reveals left overflow after r80622.
