version 1.21.0 build 25472684 Win10 (and Android 1.21.0)

Summary:

Add-Ons or worlds using the /title command (or signs) can have the text censored mistakenly when uploaded to Realms. Very likely relates to https://bugs.mojang.com/browse/REALMS-10537

Impact:

Our Add-On "Info Items Add-On" has a "Biome Sensor" that uses the /title command to display the text: "§a§lBiome: River" as an example. When the Add-On is applied to Realms, this text gets censored and displays no characters. This has resulted in a fair number of negative reviews.

Repro Steps:

Enter a Realm with cheats enabled
Enter the command:
```
/title @s actionbar §a§lBiome: River
```

Notice that the actionbar displays a small empty box without any text.
Enter the command:
```
/title @s title §2Biome
```

Notice that the title is converted to # symbols due to being censored.
Place a sign and paste the following text into it:
```
§rBiome
```

Notice that the sign text is quickly converted to # symbols due to being censored.

Observed Results:

Any text field that uses the section symbol (§) followed by the word Biome (and likely others) is censored.

Expected Results:

The word "Biome" should not be censored.

Notes:

Using /titleraw with rawtext is a viable workaround to the Realms censor (while still following the game's usual censor)
