add workaround to avoid emoji picker to take the full screen height

The toggleEmojiPopup method is a hacky workaround to avoid bug #1914
As the bug happens only for the very first time when the popup is opened,
it is closed after some milliseconds and opened again.

200 milliseconds seems to be a good value to initialize the popup correctly with the desired size

downside: there is even some flickering when opening the "more emojis" window
