{artist} is not work properly on Now Playing Widget

[idumees]

Describe the bug

Just enter {artist} and nothing will come out.
But if you enter {artist}1, the artist name1 is displayed.
That is, {artist} does not output anything by itself, but if entered like any other, the artist name is normally displayed.

For example,

{aritst}
-> NOTHING

{aritst}-{album}
-> IU-Palette

{aritst}1
-> IU1

This is it.

Affected input device

MacBook Touch Bar

use this "{title} ㅤ"
there are 2 empty characters
Must be more than two characters to display properly
