OOM in StyleBuilder::build on a 64bit platform? Do we allocate a lot in that function?

I don't quite understand how this can happen...

Comment 2

[Emilio Cobos Álvarez (:emilio)]

Me neither, build allocates a single style context, and an Arc, as far as I can tell...

I can simply reproduce the OOM from this site: http://www.robohornet.org/#et=css_selectors

STR:
1. Click the RUN button on the top right side.
2. The test runner window appears and scroll down the list.
3. Tab frozen and go to watch memory usage, e.g. macOS Activity monitor/Memory.
4. Memory usage growing until OOM.

Yes, for other cases, they are about MP4 demuxer. I think we can dupe this bug.
