@angular/core is vulnerable to Cross-site Scripting (XSS)

Medium Risk
This Affects:
@angular/coreTL;DR
The attribute pipeline previously consulted an event-attribute helper only inside development-only branches while still routing values into setElementAttribute for real renders. The runtime path now relies on compile-time and schema enforcement so on*-style attributes are not accepted through the host-attribute instruction path intended for production bundles. Supporting integration tests were updated to match compile-time failure behavior instead of expecting late runtime rejection alone.
