We're in the process of migrating to Touch UI and hope to be fully
converted by end of June. In the meantime, our authoring team is still
using the Classic UI. I just discovered an issue with the
html5smartimage widget type where the renditionSuffix property doesn't
get picked up by the widget once it's set. I'm able to set the
fallbackRenditionSuffix and it works, but not the renditionSuffix
property.
