[Bug] Blur+ removes tint from sign editing and does not blur background

[fl2mex]

Self explanatory title
Version: 1.21
Fabric Loader Version: 0.15.11
Mods installed: Fabric API (0.100.6+1.21), Mod Menu (11.0.1), YACL (3.5.0+1.21-fabric), Blur+ (4.1.0)

To recreate:
Place or edit a sign, background is supposed to be tinted in unmodded, and i'd infer it was supposed to be blurred with Blur+ installed
