Telegram для Android, похоже, не поддерживает `launchMode = singleTask` для приложений обработки файлов

Question

У меня есть Android-приложение, которое должно открывать файлы Json из приложений обмена сообщениями, но всегда в одной задаче. Никогда не должно быть двух запущенных приложений. Итак, я установил launchMode="singleTask". Вот фрагмент манифеста:

 <activity
    android:name=".MainActivity"
    ...
    android:launchMode="singleTask"
    <intent-filter>
      ...
    </intent-filter>
    <intent-filter>
      <action android:name="android.intent.action.VIEW" />
      <category android:name="android.intent.category.DEFAULT" />
      <data
         android:scheme="content"
         android:host="*"
         android:pathPattern=".*\\.json"
         android:mimeType="*/*"
       />
    </intent-filter>
  />

Это работает во всех протестированных мною приложениях, кроме Telegram. Telegram открывает новое действие внутри своей задачи. Это показано в выводе adb shell dumpsys activity activities, для com.myApp есть два отдельных действия, и одно находится в Задаче Telegram:

Опять же, это не происходит в других мессенджерах (Сигнал, Whatsapp), в соответствии с режимом запуска singleTask. Кто-нибудь сталкивался с подобной проблемой? Есть ли обходной путь?
