This has been fixed internally and will be available in the Fragment 1.3.0-alpha01 release.
Description
Version used: 1.2.1
If you use a FragmentContainerView in an XML layout and use the layout preview, an error will be printed in the preview's errors view:
```
The following classes could not be instantiated:
- androidx.fragment.app.FragmentContainerView (Open Class, Show Exception, Clear Cache)
Tip: Use View.isInEditMode() in your custom views to skip code or show sample data when shown in the IDE. If this is an unexpected error you can also try to build the project, then manually refresh the layout.
Exception Details
java.lang.UnsupportedOperationException: FragmentContainerView must be within a FragmentActivity to be instantiated from XML.
at androidx.fragment.app.FragmentContainerView.<init>(FragmentContainerView.java:117)

at org.jetbrains.android.uipreview.ViewLoader.createNewInstance(ViewLoader.java:404)
(omitted)
```
It might be good to add a check for isInEditMode, or alternatively remove the constructor overloads that throw (since the default Context-only one doesn't throw).
