fix: text events propagate out of shadow root.

[sainthkh]

• Closes Event listeners not working in custom elements #17531

User facing changelog

Typing events now correctly propagate out of the shadow DOM.

Additional details

• Why was this change necessary? => By default, text events don't propagate out of shadow root. This behavior sometimes causes some unexpected failures.
• What is affected by this change? => N/A
• Any implementation details to explain? => I followed the convention of cy.click() fixed at simulated mouse fixes, rightclick, dblclick #3030.

How has the user experience changed?

Before: Text events don't propagate out of shadow root boundary.
After: They do.
