Nullish Colaescing Operator ?? causes an error

[xavi-mat]

It seems that Minify can't manage the nullish coalescing operator. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Nullish_coalescing_operator

I'm trying to minimize this:

const a = document.nonExistent ?? "Not found";

And get:

Minify failed: Unexpected token: operator (?)

Am I missing something?

Can confirm this also happens with something?.something syntax. The ? causes the next token to be unexpected

Yes, It also can be confirmed that optional chaining ?. causes an "unexpected punc(.)" error.
