## What is the current behavior?

Due to some recent unknown changes, the intersection observer for date
time no longer reliably fires, especially in mobile views.

## What is the new behavior?

In this PR, we're adding a visibility check after everything has had a
chance to render to make sure we're setting up properly even if the
intersection observer has failed to trigger for some reason.

## Does this introduce a breaking change?

- [ ] Yes
- [X] No

## Other information

Since the intersection observer is being set up after a `raf`, it's
possible something got introduced to make the initial setup slower for
some reason, causing timing issues. I think we should do a more thorough
investigation into the cause of this problem when we have more time.

This PR also adds tests to verify the new fallback works properly.

Current dev build:
```
8.7.10-dev.11763478209.1d9c4cd8
```
