Realms error messages display raw HTML instead of readable text

When an error occurs while connecting to Minecraft Realms, the error message is rendered as raw HTML-formatted text rather than a properly localized, human-readable error message. This significantly reduces usability and makes it difficult for players to understand the cause of the failure.

Instead of displaying a normal error dialog, the client shows HTML tags (e.g., <span>, <div>, <br>, etc.) directly in the error text, suggesting that the message is not being parsed or sanitized correctly before display.

Steps to Reproduce:

1. Launch Minecraft Java Edition.

2. Navigate to Minecraft Realms.

3. Attempt an action that triggers a Realms-related error (e.g., joining a Realm during a service issue, or connection failure).

4. Observe the error message shown to the player.

Expected Result:
Error messages should be displayed as plain, user-friendly text consistent with other Minecraft error dialogs, without any visible HTML markup.

Actual Result:
The error message is displayed with raw HTML formatting visible to the user (e.g., HTML tags rendered as text).
