LGTM.  Do we (I?) need to add a test for changed behavior here?  I'm sure I may have gotten this function wrong in my initial implementation.

I tried, but it involves enabling frame flattening in Chromium DRT.  That's easy enough through internal.settings, but it looks like someone already tried this https://bugs.webkit.org/show_bug.cgi?id=87149, which lead me to https://bugs.webkit.org/show_bug.cgi?id=87993 at which point I cried and gave up.

I see, these are frame-flattening only paths?  Should we add a mac-only test?

Oh yeah, I could write a test and verify it using Qt or GTK+.  I'll add a test and re-upload.

I really appreciate your thoroughness.  Thanks.

We should CC whoever wrote frame flattening.  I don't have enough knowledge to know if this is correct or not.

[Eric Seidel (no email)]

I think Kenneth did.

I take it we don't need this scrollable-case code?  I would not trust the flattening tests to be comprehensive (that isn't to say we regard this code as sacred or shy away from changing it).

Sorry, didn't see Eric's comments.

Don't let me stand in the way of your commit. :)  Just trying to do my reviewing-due-diligence. :)  (Also since I was the last to touch this code, I guess I'm supposed to make sure it stays working...)

I believe that is already covered by RenderIFrame::flattenFrame(), which also looks at scrollingMode() and does the isFixed() checks.

OK.
