This is what I have planned. Obviously I'll have to add some more tests (not as
easy, since we easily trigger a real OOM before reaching an invalid string
length for a lot of cases).

I also need to find out what layout tests need to be rebaselined.

LGTM if you add some more test cases.

This CL now relies on https://codereview.chromium.org/196133030/
We still do not throw if allocation fails the max length comparison. Will work
on that in a separate CL.
