Thanks for reporting this. I’ve managed to reproduce the behaviour. I also note
that this doesn’t happen without the italic markers, i.e.

┌────

Is fine, while your original example,

┌────
│ /Diesen Text habe ich leicht abgewandelt schon am Montag per E-Mail ans
│ [[https://km-bw.de/,Lde/startseite/service/kontakt][Kultusministerium BW]] geschickt. Da hatten wir noch 2 Wochen./
└────

Causes issues. I also note that in the Org-mode buffer the comma seems to cause
issues. I’ve attached a screenshot, in which you can see in the “comma, italics”
situation:
⁃ The second line is not italic
⁃ The second `/' of the pair is shown (and I have Org’s entity hiding setting enabled)

All the best,
Timothy
