Crash when using a header

[ffolkes]

When using a header, I'm getting this crash. I'm running Android 12. The dialog opens fine once, but once dismissed and opened again, it crashes with this:

java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.

How do you add header view?
