Shared Workers no longer work after page reload

[ebbejan]

Current behavior

Shared Workers no longer work in E2E tests after a cy.reload().

Steps to reproduce:

1. Visit page with shared worker
2. Reload page

The Shared Worker works correctly when the page is initially loaded. The error only occurs after the reload.

Only the latest Chrome versions (tested with 119) seem to be affected. The problem does not occur in Firefox 119.

Desired behavior

Shared workers continue to function correctly in E2E tests even after a page reload.

@ebbejan Thank you for the reproducible example. I can see the test you provided is failing starting in 13.3.3. I'd suggest downgrading to 13.3.2 for the time being while we investigate.

@ebbejan the fix on #28254 should resolve your issue. We are hoping to have that released in the next few days.
