How to get ExtendedFloatingActionButton to behave similar to FloatingActionButton when interacting with CoordinatorLayout and scrolling?

Nobody has claimed this yet.

Trying to use the new `ExtendedFloatingActionButton`. It seems by default `ExtendedFloatingActionButton` acts differently from `FloatingActionButton` when interacting with `CoordinatorLayout`. See here the red one is the typical `FloatingActionButton` and the 2 black ones are the `ExtendedFloatingActionButton` with exactly the same setup (except for colors and text).
What I need is for the black ones to hide away just like the red one does.


Here's the layout:
```

```

I see in source that there's a nested class `ExtendedFloatingActionButton.ExtendedFloatingActionButtonBehavior` and it seems to have maybe some properties that might be useful/related to this such as `autoHideEnabled` and `autoShrinkEnabled` but the class is protected and I can't figure out how it is meant to be accessed.
Please help.

Start by reading ExtendedFloatingActionButton.ExtendedFloatingActionButtonBehavior and the autoHideEnabled and autoShrinkEnabled properties mentioned in the issue, then compare its CoordinatorLayout interaction with FloatingActionButton. Reproduce the supplied layout and scrolling behavior; done means the extended buttons hide or otherwise match the requested FloatingActionButton behavior, with coverage for the demonstrated setup.
