We'd like to experiment with full parsing since we are seeing very good performance results locally. To do this, we'd need a pref to enable the behaviour.

I suspect enabling this pref causes Firefox to get permanently broken with only a "refresh" fixing it, just flipping the pref back off does not fix the issue.

Websites get broken JS with the following message in dev tools "Uncaught Error: CompileOptions mismatch between input and Stencil <unknown>:1".
