Alpha server inventory item clicking broken with 1.17.1+ client

[RaphiMC]

When clicking on items inside a chest on an alpha 1.2.6 server with a 1.17.1+ client the cursor item is invisible. Very likely a ViaVersion issue because it works with <=1.17 clients.

To be honest, you can't translate the version too far away. The 1.17+ transaction packets and clickwindow packets are very different from versions below 1.8. If you wanna do this, please fix the packets yourself on 1.17+ client.
