Description of the problem including expected versus actual behavior:
The mod Travel Anchors makes it possible to teleport outside Compact Machines using either the enchant it adds, Teleporting or the Staff of Travel.

Steps to reproduce:
Go into a Compact Machine
Get a Staff of Travel with energy
Teleport outside by right clicking with the Staff of Travel in-hand (might be shift-right-click, can't remember ^^)

Original issue: EnigmaticaModpacks/Enigmatica6#1616

Should now be closed due to teleport handling in commit aef304d, which blocks all non-tp and non-ender pearl teleports.

As a thought why not use this to be able to teleport to compact machines on the wall teleporting through or just teleport out.

Going to keep this one open until I can solve this; it not really a bug so much as unimplemented functionality right now. Goal here is to eventually add a generic entity teleport event to Forge, so I can catch any modded teleporters and disable them from happening.

Update: Shrimp has made a new set of events to help this out. Tracking it here:
