WISIWIG editor does not cooperate with the clipboard consistently

### Steps to reproduce

1. I type Apple-key b (for bold) then b then Apple-key b (to end bold) and n and a blank
2. I see **b**n (as expected)
3. Then I type Apple-key a (to select all) and I see the 3 letters marked as selected
4. Then I type Apple-key c to copy the 3 letters to the clipboard
5. Then I type Apple-key v to paste the 3 letters again.
6. I see **bn **, i.e. the 3 letters replace the existing letters, but the change from bold to non-bold is lost

### Outcome

#### What did you expect?
I expect that the markup-info in the text is honored by the editor when using copy-paste

#### What happened instead?
The markup-info of the beginning supersedes any changes in the string.
