Closes #3751: Do not set pending intent on media notification for custom tabs.

        val data = state.toNotificationData(context)

        return NotificationCompat.Builder(context, NOTIFICATION_CHANNEL_ID)

        val builder = NotificationCompat.Builder(context, NOTIFICATION_CHANNEL_ID)

            .setSmallIcon(data.icon)

            .setContentTitle(data.title)

            .setContentText(data.description)

            .setContentIntent(pendingIntent)

            .setLargeIcon(data.largeIcon)

            .addAction(data.action)

            .setStyle(androidx.media.app.NotificationCompat.MediaStyle()

                .setMediaSession(mediaSession.sessionToken)

                .setShowActionsInCompactView(0))

            .build()

        if (!state.isForExternalApp()) {

            // We only set a content intent if this media notification is not for an "external app"

            // like a custom tab. Currently we can't route the user to that particular activity:

            // https://github.com/mozilla-mobile/android-components/issues/3986

            builder.setContentIntent(pendingIntent)

        }

        return builder.build()

    }

}

    val largeIcon: Bitmap? = null,

    val action: NotificationCompat.Action

)

private fun MediaState.isForExternalApp(): Boolean {

    return when (this) {

        is MediaState.Playing -> session.isCustomTabSession()

        is MediaState.Paused -> session.isCustomTabSession()
