!translate trigger is not always triggered on mobile when copy paste

[rubo77]

If you copy paste this line here directly from github in the browser on android (i use Brave) and paste it into a riot chat with the bot, the bot is not responding:

 !translate en ru Hello world.

this is the resulting source of the message:

{
  "unsigned": {
    "age": 49358
  },
  "type": "m.room.message",
  "sender": "@rubo77:matrix.myserver.de",
  "content": {
    "format": "org.matrix.custom.html",
    "msgtype": "m.text",
    "formatted_body": "!translate en ru Hello world.",
    "body": "!translate en ru Hello world."
  },
  "origin_server_ts": 1566645917777,
  "event_id": "$iP_ba9xsEqTVAjxxxxxxxiHg2-Gco2HFkGW4oEc",
  "room_id": "!SbVxxxxxxxxBEeQ:matrix.myserver.de"
}

While copy paste on PC using Chrome and riot-web works fine, this is the resulting message:
