Does Cypress sometimes break Angular change detection?

I was writing a test using the cy.realHover command provided by cypress-real-events to verify that options in a menu component are highlighted when mousing over them. However when the tests failed I noticed that the option highlighting wasn't working even when I tried it manually in the test window. However when I open the test harness page (a Storybook iframe page in this case) the highlighting works as expected. The component is built with Angular and the highlighting is triggered via a mouseover event binding coupled with a class binding that applies a css class for highlighted options. From my testing it appears that the mouseover event is firing but the class binding isn't being updated. I'm probably just going to put this test aside since it's not critical but I'm curious if there's a known issue with Cypress interfering with Angular change detection.
