Cypress contains taking a lot of time to "resolve"

[zzBrunoBrito]

I'm trying to understand why the first code takes a lot of time to run (more than 1 minute sometimes) and the second code runs like in 1 second. Any ideas?
Note: I'm mocking the requests using intercept, so I don't understand why the first approach takes so much time to finish.

cy.visit(myUrl);
cy.contains(/.*text I'm looking for.*/i).should('be.visible');

cy.visit(myUrl);
cy.get('h1').contains(/.*text I'm looking for.*/i).should('be.visible');
