Pages from CodeSandbox urls are blank on `cy.visit()`

Current behavior:

I’m trying to naviage to an app using cy.visit. The app url is *use any csb test app/. However cy.visit loads the page as a blank white page.

Desired behavior:

The page should actually load and display items.

Test code to reproduce

describe('random test',function(){
  it('Logins in to sandbox',function(){
    cy.visit("https://ky998.csb.app/")
  })
})

Versions

Cypress 5 , MacOS and Windows, Google Chrome, Electron and Firefox

Heads up, the following code sandbox url works fine in cypress

‘https://ti2os.csb.app?standalone’

Note the use of ?standalone on the preview URL from the codesandbox.

Cypress will load the sandbox url (e.g. https://codesandbox.io/s/goodbye-daft-punk-ti2os?from-embed), even the sandbox embed URL (https://codesandbox.io/embed/goodbye-daft-punk-ti2os), but it won’t load the preview URL for a sandbox (e.g. https://ti2os.csb.app/). I’ve asked codesandbox.io support if they have any thoughts.
