Current behavior 😯

It's not possible to fetch new dog images in the respective template app unless a sub breed is defined. This seems to be because the " sub breed" input now defaults to "January" when it's empty, which is one of the default values for the Select component.

Expected behavior 🤔

It should be possible to fetch new dog images in the respective template app even if sub-breed is empty, or has no options.

Steps to reproduce 🕹

Steps:

1. Make new app from the "Fetch images" template (app that fetches dog images according to breeds).
2. Try to fetch an image.
3. No new image is fetched - the default image stays the same.

It looks like the defaultValue implementation isn't the right one for this use case. I wonder whether we should revisit what defaultValue means.

• Now it means: "in the runtime, when an evaluated binding for a prop is undefined use the defaultValue instead".
• Perhaps it should mean "in the runtime, if a prop doesn't have a binding, use a const binding of defaultValue"?
