Expected behavior: Should expand BottomSheet successfully.

Source code:

class CustomBottomSheetBehaviour(context: Context, attrs: AttributeSet) : BottomSheetBehavior<View>(context, attrs) {

    private var bottomSheet: View? = null

    fun setBottomSheet(bottomSheet: View) {
        this.bottomSheet = bottomSheet
    }

    fun show() {
        if (state != STATE_EXPANDED) {
            state = STATE_EXPANDED
        }
    }
}

Android API version: Android API 27+ (Mostly on Android API 30)

Material Library version: 1.0.0

Device: Huawei Mate 10 lite, Samsung Galaxy A10s, Redmi 9A, Samsung Galaxy A21s, etc.

It's been more than a month. Any update regarding this?

Is there a specific instance in which you are calling this show method to change the state? I am currently unable to replicate this on the pixel 4 or 5.
