This reverts PR #13266 and adds a regression test for #13557. After thinking about it for a bit, my patch proposed in the issue is not the right approach; #13266 was actually incorrect and should be undone.

The interface instance passed to emitKeypressEvents() is explicitly not for decoder lifetime control; it is just used to toggle tab completion on it. We provide emitKeypressEvents() as a standalone method as well, which should work on its own exactly as documented (i.e. independently of any readline interfaces by default).

My initial suggestion of removing the keypress decoder from the stream completely might leave partial reads in the string decoder unread, which we also want to avoid.

@gibfahn Don’t worry about it, it really isn’t obvious that that would be a breaking change. This will go out with the next 8.x release and the world will keep turning. ;)

Breaking stuff happens. As @addaleax said, this one is super non-obvious and, on its face, not an incorrect change. This largely underscores the importance of growing our ecosystem testing, tho

When will a new version be released?
Nodesource only hosts the latest one so rolling back is a PITA

@Pajn That’s mostly a question for @nodejs/release but I would assume Monday or Tuesday. I should be able to prepare it that helps.

If no one else has started the release proposal by Monday I'll kick it off with an eye towards releasing on Tuesday.
