cy.getCookie() does not support timeouts

Current behavior:

Both of the following lines result in expected null to exist although the cookie becomes available within a timeframe of about 200ms:

cy.getCookie('token').should('exist')
cy.getCookie('token', { timeout: 5000 }).should('exist')

Adding a cy.wait(1000) above the lines will make them pass without error.

Desired behavior:

• cy.getCookie should use the default timeout when used together with ‘should’
• cy.getCookie should support the timeout argument as documented here: https://on.cypress.io/getcookie#Arguments

Steps to reproduce:

Use cy.getCookie('someCookie').should('exist') for a cookie which is saved with a little delay, e.g. session cookie after login.

According to the docs for .should():

Assertions are automatically retried until they pass or time out.

However you can see from the video that this fails on the first assertion, and does not retry

Hi @jennifer-shehane,

I dont think 30 seconds timeout exists. Any particular version to look out for?

Also, passing a timeout param would be great!

Thanks!
