Fixed an issue where media playback would not use hardware acceleration properly when using MSE. This would cause high CPU usage and/or choppy playback for HD video on e.g. YouTube.
Fixed ES6 iterator chains to be spec-compliant.
Fixed ES6 vector append calls and some related memory leaks.
Added a workaround to reduce the likelihood of a potential rare (timing-critical) crash.
