Why isnt cypress honoring my timeout for a single command?

I'm a couple of weeks into cypress test automation (cypress V12) and while it seems cool I am confused by what I am seeing.

I have code that looks like this:

    it('shows the problem for Stack Overflow', {defaultCommandTimeout: 20000}, function () {
      //bunch of commands that do stuff are here but I dont think they are related to the issue...

      const loadingSpinnerLocator = ".k-loader-canvas";
      cy.get(loadingSpinnerLocator).should('be.visible');
      cy.get(loadingSpinnerLocator).should('not.exist' ,{ timeout: 15000 });          

    })

this code works fine because I am doing a workaround in the top line and overriding the defaultCommandTimeout to 20 seconds.

If I remove the override on the "it statement" the test fails when we are making sure that the spinner is gone after 4 seconds. Isn't my code saying to look for 15 seconds???

How do I tell cypress to "wait up to 15 seconds for the loading spinner to not be there" without bumping up the timeout for the whole test??

Generally speaking, { timeout: 15000 } is an options object.

All Cypress commands are documented with a Syntax section which tells you if you can pass options, for example .should()

> Syntax
> js
> .should(chainers)
> .should(chainers, value)
> .should(chainers, method, value)
> .should(callbackFn)
>

This tells you there is no options syntax for .should().

On the other hand for .get(), there are permutations that allow an options parameter,

> Syntax
> js
> cy.get(selector)
> cy.get(alias)
> cy.get(selector, options)
> cy.get(alias, options)
