Alias name for req.alias containing a dot fail to intercept

[jennifer-shehane]

Current behavior

This was first mentioned here: #3512 (comment)

Alias names containing a dot in the req.alias (like get.url) cause the cy.wait() to timeout.

This does not occur when setting the alias name within an .as() command (.as('get.url')).

Test code to reproduce

it('alias without dot', () => {
  cy.intercept('/users', (req) => {
    req.alias = 'getUrl'
    req.reply('foo')
  })
  cy.visit('https://example.com')
  cy.window().then((win) => {
    const xhr = new win.XMLHttpRequest()
    xhr.open('GET', '/users')
    xhr.send()
  })
  // ✅ passes
  cy.wait('@getUrl')
})

it('alias with dot', () => {
  cy.intercept('/users', (req) => {
    req.alias = 'get.url'
    req.reply('foo')
  })
  cy.visit('https://example.com')
  cy.window().then((win) => {
    const xhr = new win.XMLHttpRequest()
    xhr.open('GET', '/users')
    xhr.send()
  })
  // ❗️ fails, cy.wait() times out
  cy.wait('@get.url')
})
