Only WISIWIG-editing possible, when trying to correct an input - mode problems with the WISIWIG-mode

### Steps to reproduce

1. Where are you starting? What can you see? I start, with the editor set to ''show plain text''. Then I enter **b** *i* visual test; after Carriage Return the formatted line is visible. Then I try to correct it - but I do not get my input presented, instead the WISIWIG-editor mode comes up
2. What do you click?
3. More steps…

### Outcome

#### What did you expect?
I would prefer to get the data I have entered, when I try to correct my input
#### What happened instead?
The mode of the WISIWIG-editor changed back to ''show formatting''

This mode-changes happens too, if I look into another room and go back to my editing - then the mode ''show plain text'' is resetted and my partial input is gone.
