.get(url) with `useWebKit: true` in iOS does not return exact match domain cookie

See original GitHub issue

Bug

CookieManager.get('https://google.com', true) returns cookies of domain with leading dot(e.g. .google.com), but not the ones with exact match domain (e.g. google.com). This issue only happens in iOS with Webkit option on. Both cookies appear no problem if I call getAll(true).

Steps To Reproduce

Make sure you use iOS to test:

Populate cookie store with cookies having both leading dot and exact match domain, say google.com and .google.com.
Call CookieManager.getAll(true), observe both cookies exists in store
Call CookieManager.get('https://google.com', true), only the cookie with leading dot (.google.com) is returned, not the one with exact match (‘google.com’). …

Describe what you expected to happen:

Both cookies should be matched and returned when I call get(url)

Reproducible sample code

  // ios sample code
  /* set exact match domain */
  await CookieManager.set({
    name: 'foo',
    value: 'foo',
    domain: 'google.com',
    origin: 'google.com',
    path: '/',
    version: '1',
    expiration: '2021-05-30T12:30:00.00-05:00',
  })
  /* set leading dot domain */
  await CookieManager.set({
    name: 'bar',
    value: 'bar',
    domain: '.google.com',
    origin: 'google.com',
    path: '/',
    version: '1',
    expiration: '2021-05-30T12:30:00.00-05:00',
  })
  console.log(await CookieManager.getAll(true)) // foo, bar both exists
  const test = await CookieManager.get('https://google.com', true)
  console.log(test) // only bar shows up
