Dismiss DialogFragment by link click crashes the app

[Festak]

Kotlin. Device: Xiaomi. OS: 10.0
We have Fragment A, which opens Dialog Fragment. When the user clicks on the link in Dialog Fragment, we call dismiss(). And it throws an exception:

E/InputEventReceiver: Exception dispatching input event.
