Typing in a long text is buggy in firefox

[zemlint]

What is the current behavior?

• Typing in a long text that produces a linebreak is not working correctly in firefox. This effects multiple fields like the survey title, the page title, the description and question titles.

• When the end of the line is reached and you continue typing the words are written backwards. I suppose this is due to the cursor staying at the beginning of the new line.

• Example:
  

• Pasting long text is working.

• This only affects firefox (as far as I tested), chromium is working fine

How would you reproduce the current behavior (if this is a bug)?

Visit https://surveyjs.io/survey-creator/examples/free-nps-survey-template/reactjs# in firefox and type in a long title for a question. As soon as you reach the beginning of a new line, you can not type in new words correctly.
