RSSP error messages are not Line break

We are setting up the messages configured in

"■Implementation Projects-> Procurement >Search> Manage Messages" to be output as error messages on the RSSP screen.

However, the error message on the RSSP screen is not broken down into lines. I was told that this is a specification issue in SR, but I don't know the specific circumstances that led to the specification change between the SSP screen and the RSSP screen, so I'm asking here.

If not allowing line breaks is part of the specifications, I want to confirm the reasoning behind this design choice as a product.
