New line with \n doesn't work on items name or lore

When using commands to give an item with custom name and lore, the "\n" character is seen as a square, and no new line is created.

For example, when using the command

/give @a stone{display:{Name:"{\"text\":\"This is\\na test\"}", Lore:["{\"text\":\"Showing\\na bug\"}"]}}

I get the item showed in the attached picture.

Note that I escaped the backslash at the \n, if I don't, I get an error when executing the command.

If this is working as intended, I would suggest a change, as lores are sometimes long.
