[Bug] Multi-Selection in Data Extraction Form removes line breaks on edit

[andreaskrauss]

Describe the Bug:
When editing a data extraction form field which is of type Multi-Selection, the text appears in a single line. Thus, if one likes to edit the options, a user must recreate each line break.

Expected Behavior:
The text field for editing should be scaled automatically to the correct number of options and their text width. Parsifal shall load all options inclusively their line breaks (i.e., the linebreaks shall not be removed) to reduce the work to fix minor mistakes (e.g., typos) or add another option to a multi-selection field.

Do you like to contribute?
I'm sorry, but I do not have the time to do that at the moment.
