Tuples in unions does not get validated since v3.9.1

Following schema

const eventsSchema = z.union([
    z.object({
      eventName: z.literal('foo'),
      eventPayload: z.tuple([z.number().nonnegative(), z.number().nonnegative()])
    }).strict(),
    z.object({
      eventName: z.literal('bar'),
      eventPayload: z.string().email()
    }).strict()
]);

failed before v3.9.1 with following data

const data = {
  "eventName": "foo",
  "eventPayload": [0, -60]
};
const parseResult = eventsSchema.safeParse(data);
// parseResult.success === true

but since v3.9.1 zod does not validate the -60 value anymore as .nonnegative(). Parsing is always successful whereas before v3.9.1 it failed (which is the expected behaviour)

Should be fixed in 3.9.2+

Oops looks like I failed to fully roll back the changes that caused this error. I’ve confirmed that all the above cases are working in Zod v3.9.8+.
