TranslatableComponent not working on Sign blocks

Expected behavior

I expected using Component.translatable(...) would work on Sign blocks. Using server-side translations with GlobalTranslator should show the translated text to the client in a line of a Sign that uses that implementation of Component.

Observed/Actual behavior

In lines that uses TranslatableComponent, it only shows the translation key as text instead of the actual translation from ResourceBundle. I've checked the keys and they're all correct. Styles as color and decorations work well, only the text shown is the problem.

Steps/models to reproduce

Just get a Sign block from a World and try to use Component.translatable(...) to write some of its lines. Update the Sign using the SignSide method.

Here is my code:

MinigameInfo info = minigame.getInfo();
Component[] lines = new Component[4];
lines[0] = Component.text(info.name() + " " + index);
switch(state) {
case AVAILABLE -> {
lines[1] = Component.translatable("minigame.sign.available", NamedTextColor.GREEN);
lines[2] = Component.text(minigame.getWorld().getPlayerCount() + "/"
+ info.maxPlayers(), NamedTextColor.WHITE, TextDecoration.BOLD);
lines[3] = Component.text("» ONLINE «", NamedTextColor.AQUA, TextDecoration.BOLD);
}
case RUNNING -> {
lines[1] = Component.translatable("minigame.sign.running", NamedTextColor.RED);
lines[2] = Component.text(minigame.getWorld().getPlayerCount() + "/"
+ info.maxPlayers(), NamedTextColor.WHITE, TextDecoration.BOLD);
lines[3] = Component.text("» ONLINE «", NamedTextColor.AQUA, TextDecoration.BOLD);
}
case WAITING -> {
lines[1] = Component.empty();
lines[2] = Component.text("-/-", NamedTextColor.WHITE, TextDecoration.BOLD);
lines[3] = Component.translatable("minigame.sign.waiting", NamedTextColor.BLUE, TextDecoration.BOLD);
}
}
SignSide side = sign.getSide(Side.FRONT);
for(int i = 0; i < lines.length; i++) {
side.line(i, lines[i]);
}
sign.update();

No response

Reproduce the issue with Component.translatable, GlobalTranslator, SignSide.line, and sign.update on the reported Paper version, then trace how sign lines are serialized and translated for clients. Compare the handling of translatable and styled text; done means a sign displays the resolved ResourceBundle text instead of its translation key.
