Creating rtl themes

Hello everyone,
I am currently working on a base theme and am looking into adding rtl support. Has anyone else had major issues with ie6,ie7, and ie8 while using something like:

body { direction: rtl; }

Applying the direction attribute to the html or body tag seems to cause a lot of issues in earlier versions of ie. I ended up using doing this:

/* apply rtl to the html tag so the scrollbar is on the correct side /
html {
direction: rtl;
}
/ set the language direction back to left to right to avoid breaking the layout in ie. /
body {
direction: ltr;
}
/ apply rtl directly to all tags that may contain text */
p,form,input,h1,h2,h3,h4,h5,h6,span { direction: rtl; text-align: right; }

Has anyone encountered issues with ie while using direction: rtl? Am I missing something obvious? Is there any easier work-around anyone might recommend? Thanks for any help!
