problem

1. Use a task with segment based min max length so that segment length is shown in the editor.
2. Open a segment with empty target for editing.
3. Press backspace inside the empty target multiple times.
4. Nothing is visible in the editor, but segment length increases

reason

On each press character #8203 (zero length space) is added to the editor. This character is needed for proper working if editor is empty. This issue handles the fact that on each press another 8203 character is added, regardless that the editor contains only one of them and is therefore empty.

Another issue is the fact that the "zero length space" character counts as one character instead of no character. This is handled in a separate issue.
