ah! forgot to remove createAnonymousTable from RenderBlock, in a function which will be eventually removed, but good as a cleanup in this patch itself. Also, just a fyi, that bidi-override-in-anonymous-block test is disabled on other platforms, so i didnt know the right rebaseline to do.

It's too bad the rest of the code relies on that. This looks like another static function that could be split...

> Source/WebCore/rendering/RenderBlock.h:238
> +    static RenderBlock* createAnonymousColumnsWithParentRendererAndDisplay(const RenderObject*);
> +    static RenderBlock* createAnonymousColumnSpanWithParentRendererAndDisplay(const RenderObject*);

Those 2 don't take a display so the name is wrong. This is not repeated but this is a wrong pattern in your naming.

> Source/WebCore/rendering/RenderButton.cpp:53
> +        bool isDeprecatedFlexibleBox = style()->display() == BOX || style()->display() == INLINE_BOX;
> +        m_inner = createAnonymousBlock(isDeprecatedFlexibleBox ? BOX : BLOCK);

Isn't that a big FIXME that we actually don't honor our current display?

I would actually pass the display as-is and push the INLINE_BOX display check into createAnonymousBlock along with the FIXME.

> Source/WebCore/rendering/RenderTable.cpp:1280
> +RenderTable* RenderTable::createAnonymousWithParentRendererAndDisplay(const RenderObject* parent, EDisplay display)

The only call site using that doesn't care about EDisplay. I think for now we should just drop the EDisplay argument unless needed (like for replacing the isFlexibleBox boolean).

> Source/WebCore/rendering/RenderTableSection.cpp:1416
> +RenderTableSection* RenderTableSection::createAnonymousWithParentRendererAndDisplay(const RenderObject* parent, EDisplay display)

I don't think you need to pass EDisplay here. Whenever you need to create an anonymous table section, it should use TABLE_ROW_GROUP as its display value.

s/createAnonymousWithParentRendererAndDisplay/createAnonymousWithParentRenderer/

> Source/WebCore/ChangeLog:10

a new anonymous wrapper of the same type as the class, inheriting style properties...

> Source/WebCore/rendering/RenderBlock.cpp:7422
> +    // FIXME: Why are we forcing a BOX display for old flex box here ? Is this a hack for RenderButton ?

I think it should be stated more as:

// FIXME: Do we need to convert all our inline displays to block-type in the anonymous logic?

There is a function already doing that on CSSStyleSelector that we could reuse if that was going to happen (equivalentBlockDisplay).

This needs to be skipped on all other platforms as you will be breaking them if not. For Chromium something like (to be double checked against our baselines):

WK83116 LINUX WIN : fast/css/bidi-override-in-anonymous-block.html = TEXT

For other platforms, it should just be added to the Skipped file.
