** [tickets:#8298] Use jinja caching settings for EW core widgets**
**Status:** in-progress

During an upgrade of EasyWidgets from 0.2.dev to 0.3 I saw a few of these
errors. Not really a big deal, just a temporary error during a live upgrade.
But it did highlight the fact that EW was reading template files from disk that
should've been cached. The stack trace seems to miss a few lines, but jinja's
`is_up_to_date` check is running which gives enough of a clue about autoreload
being on.
