RTL document in <iframe> should have left-hand scrollbar.

• Component: WebCore Misc.
• Status: NEW ---

[Aharon (Vladimir) Lanin]

This is a continuation of bug 54623, for the case of scrollbar on an <iframe>.

Currently, it is always on the right, even if both the <iframe> and the document inside it have direction:rtl. For an <iframe>, the scrollbar should be on the start side of the document inside it (even though that is *not* the case when the same document is displayed in a separate tab, not an <iframe>). If the thing inside the <iframe> does not have a direction, e.g. it is an image, it should be on the start side of the <iframe>'s direction. (If the latter requirement is very difficult to achieve, though, it can be relaxed.)

As usual, behavior on Mac OS X is a special case.

Test case. Extract the files in the zip and open iframe-scollbar-outer.html.

A test result on IE9

Greetings Aharon,

Thanks for your bug report.
When I open your test file "iframe-scrollbar-outer.html" with IE9, it renders a scrollbar to the left side of its third iframe element, i.e. "<iframe src="iframe-scrollbar-inner.png"> as shown in the attached picture. Is it your expected one? (It seems IE9 does not allow an inner element of an <iframe> element to inherit the direction property from it.) If it is acceptable for you, it is not so hard to implement its fix. (As far as I have quickly investigated, WebKit does not allow it as well as IE9. Changing this behavior may need a discussion.)

Regards,

Hironori Bono

The picture you attached shows the third iframe with the scrollbar on the right, not the left. It is the same result that I get.

No, I want it to be on the left.

I do not want an HTML document in an <iframe> to inherit the direction of the iframe. I only think that it might be nice to have thaact happen for an image or other content types that can not specify their own direction. And even there, it is not a very important requirement. It's the first iframes in the test case that are important.
