Short description of the problem:

When showWhen or hideWhen are used in addition to the [hidden]="" directive the component will be displayed even on the platform that it should remain hidden on.

For example, if hideWhen="ios" is used on a FAB button the FAB will not initially display on iOS. But if I add [hidden]="showFAB" to the button and then toggle the showFAB value using a button on iOS the FAB will be shown once the showFAB value is toggled back to true.

What behavior are you expecting?

A component with either showWhen or hideWhen should ignore the [hidden]="" directive so it won't be shown on the wrong platform yet still allows the component to be toggled on the correct platform.
