Computed enum with number in string template is incorrect

[bvandercar-vt]

Describe the bug

The following was fine with regular rollup Vite, but now is incorrect:

enum NumberEnum {
  NUM_1 = 1000,
  NUM_2 = 2000,
  NUM_3 = 3000,
  NUM_4 = 4000,
}

enum ComputedEnum {
  COMPUTED_1 = `${NumberEnum.NUM_1}-${NumberEnum.NUM_2}`,
  COMPUTED_2 = `${NumberEnum.NUM_3}-${NumberEnum.NUM_4}`,
}

With Vite (previous, good): ComputedEnum.COMPUTED_1 is "1000-2000"
With Vite-Rolldown (not good): ComputedEnum.COMPUTED_1 is "-"

If I change the first enum to strings instead of numbers, the computed value is correct.

Computed values from numbers that don't use templates, are also good. It seems the problem arises from using a number in a string template.
