Real time editing with Froala editor is resetting the cursor position

Convergence is not performing well enough if 2 or more users are typing at the same time.
We tested it and here’s the whole scenario

user1 is typing ‘a’ continuously on line 1
user2 is typing ‘b’ continuously on line 2
when any of the user presses enter key to get on the new line then cursor position gets disturbed and eventually we ended up typing ‘abababab’ while it should be 'aaaaaaa(on line 1) and ‘bbbbbbbbb’ (on line 2). Problem may be with enter key.

We have also tested it with example from convergence - https://examples.convergence.io/examples/froala

Can you please help us to solve this issue. We need it to be solved as soon as possible.

Thanks in advance.
