+1 for this, I'm also facing this issue when upgrading babel in un-ts/babel-preset-proposal-typescript#115.

Hey guys, we have tests that start to fail with an automated upgrade of babel to v 7.14.0.
Context is a CRA with nothing fancy but I can't confirm we're hit by this exact problem, I'll provide all the details later today and create a separate issue if it's not the same thing.

Cheers,

Was this working in previous versions? If yes, I guess the bug has been introduced by #13209

[JounQin]

@nicolo-ribaudo Yes, it was working previously.
