Does crossSubDomainCookies not work on localhost?

So currently i have a setup where my login is on localhost:5173/login. here i get my cookie when i go to tenant.localhost:5173/admin i dont have the cookie the domain says localhost even tho its supposed to say .localhost from my understanding? setup: 
advanced: {
  crossSubDomainCookies: {
  enabled: true,
  domain: '.localhost',
  },
defaultCookieAttributes: {
  secure: true,
  httpOnly: true,
  sameSite: 'none',
  partitioned: true,
  },
},
advanced: {
  crossSubDomainCookies: {
  enabled: true,
  domain: '.localhost',
  },
defaultCookieAttributes: {
  secure: true,
  httpOnly: true,
  sameSite: 'none',
  partitioned: true,
  },
},
am i missing something or might this be a bug because domain expects a "real domain"?
