Calendar Links don't respect new record layouts

We have apps that have been converted to the new record layout, but when a user opens it from a calendar activity link, the record still loads in the old layout.

Steps to Reproduce

  1. Open an app that has already been converted to the new record layout.
  2. Create or locate a calendar activity associated with that app.
  3. From the calendar link, open the activity and click through to the related record.
  4. Observe that the record opens in the old record layout instead of the new converted layout.

This seems very similar to this earlier shared bug that was resolved for related item links
