problem 1 (main problem)

1. Open a segment which contains after import only one tag.
2. Try to add text before that tag
3. The text is always added after the tag, instead before.
4. Also the tag is not deletable

problem 2

1. Typing text after the tag leads to strange behaviour: when pressing a character on the keyboard, in the INS a whitespace is added, then the pressed character, when typing of the character is finished, the whitespace disappaeres and everything looks OK.
2. This is not always reproducible

problem 3

1. When clicking into the above generated INS (example the sentence "das ist test" was added, click before test to add "ein") to add additional text, this text is added at the end of the INS again, instead at the desired place.

problem 4

1. To much 8203 characters in the generated HTML code

See problem 1 - 3 in the attached video (you have to stop at second 0 to see that the cursor is before the tag)
For problem 4 there is an additional screenshot.
