Do you mind decoupling the iterator from the optimization? -I wouldn't want to rollout the iterator, in case the optimization causes regression.

Hmm, so you'd want me to land the RenderDescendantIterator first without any call site? The change to RenderBlockFlow::adjustComputedFontSizes() is pretty trivial with the iterator.

Done in https://bugs.webkit.org/show_bug.cgi?id=157785. I will rebaseline this patch when the other when lands.

Looks like this broke something. I'll take a look tomorrow.

It's a good thing I enabled autosizing on Mac for testing and landed tests.

As it turns out, the previous implementation was skipping children in this case, which is why the previous patch failed some tests.

> Source/WebCore/rendering/RenderBlockFlow.cpp:3819
> +        descendant = RenderObjectTraversal::nextSkippingChildren(text, this);

Here, it is safe to call nextSkippingChildren() instead of next() because RenderText cannot have children.
