Fix transform of unary expression in Babel plugin All of our static evaluation & dead-code elimination transforms need to happen in post-order, transforming inner nodes first. This is so that in complex nested cases all transforms see the simplified version of their inner nodes. For example: async getNimbusExperimentData() { if (!PDFJSDev.test("GECKOVIEW")) { return null; } // other code } -> [evaluation of PDFJSDev.*] async getNimbusExperimentData() { if (!false) { return null; } // other code } -> [!false -> true] async getNimbusExperimentData() { if (true) { return null; } // other code } -> [if (true) -> replace with the if branch] async getNimbusExperimentData() { return null; // other code } -> [early return -> remove dead code] async getNimbusExperimentData() { return null; // other code } This was done correctly in all cases except for our `UnaryExpression` transform, which was happening in pre-order. 2024-01-29 11:13:48 +01:00			`var k = !PDFJSDev.test('TRUE');`
