Entity selectors in /say commands are no longer evaluated

In previous versions, including entity selectors as part of the message of a /say command would display the list of entities targeted by the selector. This seems to no longer be the case in 22w18a.

How to reproduce

Open or create a world with cheats enabled and run /say @e in chat.

In 1.18.2, the message that is sent in chat includes a list of the names of all entities in the world, separated by commas. In 22w18a, the message that is sent in chat is just [playername]@e.
