dart2js: Guard against imprecise inferred types

dart2js: Guard against imprecise inferred types

For some reason html.Element's   static const _tagsForWhichCreateContextualFragmentIsNotSupported is inferred to dynamic instead of a ContainerTypeMask.

This change will also 'do the right thing' if we turn off type inference.

If this is something that should be fixed in the type inference, I think there
should at least be a TODO for this.

Otherwise LGTM.
