[minor] display bug: tabs getting intended

[ofarrill]

(sorry wrong repo - but I can't move it, nor delete it...)
...and another minimal display issue:

Between the left border and event there is only a single tab, when inserting characters before the end of the tab width:

• the tab at column 0 should not be visibly indented (until tab width characters are inserted - and then jump to the next tab width position):

It's a known issue with AvaloniaEdit.

Thanks @love-linger, I see...
