Problem
When in edit mode and entering a newline (return key on the keyboard), the behavior of the edit field is unclear.
Solution
- a newline should not insert a line break
- a newline will be ignored when entered in a focused edit field
- when being copied in an edit field a newline will be replaced with an empty string.
Open question:
How will aliases separated by pipes be copied?
Would it be possible to replace line breaks in aliases by inserting pipes or actually insert line breaks (as aliases will be separated by something similar to a newline anyhow as stated in T218690)?
