zone.js propertyPatch breaks spread for objects with Symbol keys.

[wesselvdv]

Which @angular/* package(s) are the source of the bug?

Don't known / other

Is this a regression?

No

Description

When compiling with optimizations: true in angular.json it'll enable esbuild which will transpile to ES2015 which causes spreads to be replaced with a polyfill. zone.js has a property patch that overrides Object.defineProperties where it's using Object.keys() to iterate over the properties of the object to merge into the spread. This causes all symbol keys to be omitted: Object.keys({ a: 1, b: Symbol() }) === ['a']

angular/packages/zone.js/lib/browser/define-property.ts

Lines 38 to 43 in a92a89b

	Object.defineProperties = function(obj, props) {
	Object.keys(props).forEach(function(prop) {
	Object.defineProperty(obj, prop, props[prop]);
	});
	return obj;
	};
