Sign dying broken

On a world upgraded from last year's latest 1.17 snapshot, attempt to dye a dark oak sign. I believe there's something broken by the addition of glow ink, because both attempting to dye the sign with a normal color, and attempting to make the sign glow will not work, as no visible changes to the sign occur.

Should also mention that placing signs on other signs when not shifting being broken seems to be a feature in snapshots.
