Inconsistent behaviour of "connection failed" dialog

With OH 5.2.1 i observe an issue with std. web page as well as Android APP.

Problem starts with temporary connection loss, due to e.g. Android going into sleep mode.

  • Dialog “connection failed” sometimes seems to stay, sometimes vanish although connection is back
  • In case dialog stays
    • pushing the “reload” button leads to getting loss of “<- back” in web page / getting the hamburger icon instead of back icon on Android
    • touching somewhere on the page with Android, works pretty well, i.e. dialog vanish and back icon/text is still there

After some retries i’m still not 100% sure behaviour is deterministic, i.e. above holds true in any case.
Has anybody else observed similar behaviour?
