I haven't reproduced the issue yet, but it does appear to have a clear regression point. Running the test standalone does not produce the failure.

Test list for reproducing "model-element/model-element-ready-load-aborted.html" text failure.

[Robert Jenner]

I was able to reproduce the failure at tip of tree using the attached test, and running it as:

run-webkit-test --root <path to revision> <path to test list> --debug --child-process=1

By eliminating tests from the test list, I was able to deduce that when the test: model-element/model-element-graphics-layers.html is ran before: model-element/model-element-ready-load-aborted.html it causes a consistent text failure. 

When the test: model-element/model-element-graphics-layers.html is removed, and the entire suite of 7000+ tests is ran again without it, model-element/model-element-ready-load-aborted.html passes.

Sam and I think we see the mistake in the test
