			* Fix 1: When we use the content as a selector. In this case, we can use
			* cy.contains(selector, content) instead. This is compact command which
			* will retry to match both the selector and the content.
			*
			* Fix 2: When we need an assertion about the content. In this case, we can
			* use cy.contains(selector, content) or cy.get(selector).should('have.text', content)
			* is also a good replacement.
