I just noticed recently that components that have access to the app scope and use values stored in the App's "Formulas" property no longer work unless the App has already loaded that formula outside of a component. How long has this been the case? I'm certain apps I built that used formulas in components used to work this way. The issue doesn't happen in the editor, only in play mode.
So in short, formula references in components work just fine in the Canvas App editor, and work if the there's a reference to the formula somewhere outside a component that has already been called in play mode.
Example:
Here I built a component to test this issue. One container has a Fill "hardcoded", the other has a Fill that's references an App Formula. I also display the App Name as stored in the Formulas.
In the editor all values display and render perfectly fine.
Formulas:

The Component (in editor):
Play Mode Error:
In play mode, however, none of the values stored in the App's Formulas display. The container with a fill stored in the Formulas is black, and the "app name" is blank.
Play Mode Working (with other references to the same formulas on the screen and outside the component)

This helps the component load properly in play mode:
Has anyone else noticed this issue? Is there anyway to enable the component to be able to call the formula on its own?
