I just modified some of our quirky horizontal alignment code for LTR so that it would work for RTL too, thinking it would fix bug 64490. It didn't. But we might want to do this anyway.
I'll try to reassess whether we need this after bidi lands.

Reality check. Moving out to 0.9.1.

Can you give me an idea of what a testcase would be and I will test it on my BIDI build? Thanks
(Within an RTL document:) <div align="left"> <table width="50%"><tr><td>This is a table.</td></tr></table> </div> It would be interesting to know what other browsers that support BIDI do here...
Internet Explorer 6 pretty much centers the text, whereas we right align it. I think Internet Explorer gets it right in this case, so we probably have a bug here. I think the issue is does the div align="left" become a div align="right" in the RTL case. To make it an RTL document, make it like this: <html dir="rtl"> <div align="left"> <table width="50%"><tr><td>This is a table.</td></tr></table> </div> </html>
Is the table on the left edge or right edge of the page? And where is the text within the table? (Sorry... should have been clearer that the split between those 2 questions is what is important...)

So I think I have some bugs, but I should see if they exist without my patch...
Target Milestone: mozilla0.9.2 → Future
Konqueror is completely broken with Mike Kaply's simple <div align="left"><table>...</table></div>, so I guess we can only trust IE on this. How come such an important patch is still waiting? Waiting for testers, or an R/SR?
It's waiting because I don't know what, if anything, is really necessary (it would be nice to see a screenshot of IE displaying the most recent testcase -- I could probably produce one when I have access to a Windows box later) and because the patch is, I think, somewhat broken.

No activity for last 2 years, still present in Mozilla 1.5. The problem is very simple: in left-aligned RTL context, tables are aligned to the right, while everything else (text, images) is aligned to the left. As you can imagine, this arises in practice. Trivial testcase: <html><body dir="rtl"><div align="left"> FOO <table><tr><td>BAR</td></tr></table> </div></body></html> Mozilla right-justified "FOO" and left-justifies "BAR", while MSIE puts both on the left. Konqueror does the same as Mozilla. The HTML and CSS specs, as far as I can tell, leave this defined. Logic, consistency and installed base clearly support the MSIE behavior.

Any progress on this bug? As mozilla2eran@tromer.org mentioned, the test case is very simple. Furthermore, if you modify that test case to: <html><body dir="rtl"><div align="left"> FOO <table align="left"><tr><td>BAR</td></tr></table> </div></body></html> You will see it fixes the problem. The bug seems to be as simple as a table not inheriting the align attribute on a dir="rtl" page. Whereas, on a dir="ltr" page, tables *do* inherit an align="right" attribute. Matt
Target Milestone: mozilla1.7alpha → mozilla1.8beta3
Comment 19 is quite misguided; what's inherited is very different from align="left" on tables, which is floating, not block-alignment. In any case, I'll post an updated patch shortly. I'd note that my simple request for a screenshot from somebody who used Windows took almost a year, so please don't complain about it being slow.
