[PP-1] Prevent more scenarios where a user may navigate from inside the preview iFrame

Removing [PP-1] - I don't see anything remaining preventing this from being worked on.

Funny enough, I just articulated a proposed solution on a related issue: #3492358-21: Provide API to allow component instances to behave differently while being previewed → .

Hi,

I've written a Cypress test case for this, and the component renders correctly in the Cypress preview. However, the JavaScript behavior doesn't seem to apply inside the iframe. Specifically, when clicking the link, the alert dialog that normally opens in the actual preview page is not triggered during the Cypress test.
It behaves as expected in the real preview (as shown in the attached video), but not in the Cypress iframe environment.
Do we need to make any additional changes or configurations to ensure the JavaScript inside the iframe behaves the same way during testing? Attach video for the same.
