- prefers insertAdjacentHTML over innerHTML as it's much faster in this case (about 5x)
- memoizes tz.guess()
- memoizes list of timezones
- inlines template
- applies main element class in one pass
All in all for a very edge case of about 80 dates it should be faster of about 15/20ms.
* Remove long-deprecated method
* FIX: Memory Leaks when decorating posts
Previously we'd keep creating mixins dynamically when decorating the
same class.
This code changes the API to recommend an `id` parameter for each
decorator which will avoid leaks. All plugins should be updated to
include this parameter, although if they don't in the meantime it'll
just mean a warning in the console (and a continued leak.)
