Steps to reproduce:
- Have non standard decimal symbol (comma) and arguments separator (semicolon);
- In a math region type A,b
- Without leaving the region (if auto calculation is enabled, otherwise it applies always) , select and copy the text
- Try to past as math > doesn't works
- Try to paste as plain text > terms aren't serialized in standard plain text (period as decimal separator, comma as argument separator)
