WebKit Support - The application does not load using cypress webKit for Safari Browser only, it throws unhandled exceptions for JavaScript libraries

[Ranjeet-NBLY]

Cypress Automation testing issue:
Issue: The application does not load using Cypress WebKit for Safari Browser only, it throws unhandled exceptions for JavaScript libraries

Solutions Applied:
Root cause Identified: Figured out that CDN of single-spa(cdn.jsdelivr.net) UI library version [email protected] was throwing an unhandled exception
Solution 1: Removed the CDN and loaded code from the application server itself using import-maps
Result: Application started breaking because it was not supporting the import map for single-spa

Solution 2: Upgraded the library version from '[email protected]' to '[email protected](Latest)'
Result: Same error

Solution 3: Changed the CDN provider from cdn.jsdelivr.net to unpkg
Result: Same error

Note: Application supports >=13.5 Safari versions, Application does not load properly in less than 13.5 Safari version (It does not load a few icons/buttons/images).

There was no provision in the cypress WebKit to configure Safari browser versions so we are not sure about default Safari version supported by the WebKit. It seems this WebKit is not compatible.
