LCTRL + Middle Click no longer copies 1:1 exact copy of the sign?

[andrew121410]

Expected behavior

I would expect the sign copied using LCtrl + Middle Click to be the exact same sign as the sign I manually created?

Observed/Actual behavior

The copied sign losses it's colors entirely, or the formatting on the sign gets messed up.

Steps/models to reproduce

Create any sign using any method of creating the sign, commands or custom plugin, then copy the sign and place it.

This is also reproducible in singleplayer worlds on version 26.3, so this is fault from Mojang.
