BDS 1.21.130.4 doesn't support blocks with "use_beta_features" tag

When attempting to connect to a dedicated server running a world utilizing an addon with block(s) containing “use_beta_features”: true, you will receive a “Blocks between client and server do not match.” error.

What I did

Attempted to connect (from a desktop, Switch, and Android, all running 1.21.130) to a BDS 1.21.130.4 instance running a world with an addon utilizing blocks with the “use_beta_features” property.

What happened

Received an error: “Blocks between client and server do not match.”

What I expected to happen

The Minecraft Bedrock 1.21.130 client(s) should have connected to the dedicated server.

Repro Steps

• Created a world in Minecraft 1.21.130 for Windows, added an addon that contains blocks meeting the above criteria, applied appropriate experimental toggles, and launched the world, as a control test - the world loaded fine.

• Placed the behavior and resource pack used into the world folder (and removed from development folders), relaunched Minecraft, and re-tested - the world loaded fine.

• Copied the world from the minecraftWorld folder into the world folder of a new BDS 1.21.130.4 instance and launched. Attempted to connect from desktop client and received the “Blocks between client and server do not match” error message.

• Shut down the server. Removed all files from the Behavior Pack’s “blocks” folder that contained “use_beta_features”: true, relaunched the server and watched all the missing reference errors flow by.

• Attempted once again to connect from the desktop client - the client connected successfully.
