UI: "Found undefined alias for 'myalias'" when multiple aliases defined for element

Current behavior:

When using .as('myalias') in a loop the message Found undefined alias for: 'myalias' shows up in the UI but it still works (in the console you can see that the alias resolved to two elements).

The message does not show up when the loop is only executed once.

Desired behavior:

This message should not appear and irritate the developer 😃

Steps to reproduce: (app code and test code)

describe('Test', () => {
  it('test', () => {
    cy.visit('http://google.com');
    for (let i = 0; i < 2; i += 1) {
      cy.get('[name="btnK"]').as('search-button');
      cy.get('@search-button');
    }
  });
});

PS:

Am I using aliases incorrectly here or is this just a misguided message from the UI?

Oh, yeah, this is a bug. This isn’t even concerned with the loop, it seems that when using aliases for elements, if more than 1 is matching, the UI messes up a bit and displays this undefined message.

I believe this was introduced in this PR https://github.com/cypress-io/cypress/pull/2960

Code to reproduce:

it('test', () => {
  cy.visit('http://google.com')
  cy.get('[name="btnK"]').as('search-button')
  cy.get('@search-button')
  cy.get('[name="btnK"]').as('search-button')
  cy.get('@search-button')
})
