EntityPortalExitEvent is never called

[Trigary]

What behaviour is expected:

One of the following two:

• EntityPortalExitEvent to be called
• EntityPortalExitEvent to be deprecated and it's JavaDocs to explain that it is never called

What behaviour is observed:

The event is never called by neither Paper-Server nor Paper-API.

Steps/models to reproduce:

• Running the following command in the Paper (workplace) root directory shows us that the event is never fired: grep -r --include *.java EntityPortalExitEvent Paper-*
• No deprecation, etc can be observed in the JavaDocs: https://papermc.io/javadocs/paper/1.16/org/bukkit/event/entity/EntityPortalExitEvent.html

Plugin list:

None / NA.
