Can't scroll up if there is a draff

[adbenitez]

if I write something in the text area, then try to scroll up the message list, to read a previous message related to what I am writing, the app keeps moving the scroll to the bottom every second, making it impossible to scroll up, in the console I see constantly a repeated event that is calling messageList.setDraft():

2379.9s [D]main/ipc: EVENT_DC_DISPATCH:  messageList.setDraft [ 14, 'some text' ]
2380.2s [D]core/event: DC_EVENT_MSGS_CHANGED 14 0
2380.2s [D]main/deltachat: sendToRenderer: DC_EVENT_MSGS_CHANGED [ 14, 0 ]
2380.2s [D]main/deltachat: sendToRenderer: DD_EVENT_CHATLIST_CHANGED {}
2380.2s [D]main/deltachat: sendToRenderer: DD_EVENT_CHATLIST_ITEM_CHANGED { chatId: 14 }
2380.2s [D]main/deltachat: sendToRenderer: DD_EVENT_CHAT_MODIFIED { chatId: 14,
  chat:
   { id: 14,
     name: 'SimpleBot🤖',
      isVerified: false,
      profileImage: null,
      archived: 0,
      subtitle: 'simplebot@riseup.net',
      type: 100,
      isUnpromoted: false,
      isSelfTalk: false,
      contacts: [ [Object] ],
      contactIds: [ 19 ],
      color: '#76c84d',
      summary: undefined,
      freshMessageCounter: 0,
      isGroup: false,
      isDeaddrop: false,
      isDeviceChat: false,
      draft: 'some text',
      selfInGroup: false } }

I guess the scroll to bottom is because this draft is causing DD_EVENT_CHAT_MODIFIED constantly, if draft didn't changed it shouldn't be fired.
