[BUG] Comparison with -0 using the "===" operator will also match 0 [equals-negative-zero]

[atali]

Describe the bug

When using supabase with ssr and compiling I got the following warning : Comparison with -0 using the "===" operator will also match 0 [equals-negative-zero]

There is a similar error reported here #321

I have made the following repo to reproduce the error, you just need to run npm run cf:build

npm run cf:build

> open-next-equals-negative-zero@0.1.0 cf:build

  Floating-point equality is defined such that 0 and -0 are equal, so "x === -0" returns true
  for both 0 and -0. You need to use "Object.is(x, -0)" instead to test for -0.
