I omit fullscreenerror here so it falls back to default below.

How did you test this change?

Added unit tests.

Greptile Summary

This PR adds support for the onFullscreenChange and onFullscreenError React event handlers, mirroring facebook/react#34621. These map to the native fullscreenchange and fullscreenerror DOM events.

• Adds fullscreenerror to the DOMEventName Flow type union (alongside the pre-existing fullscreenchange)
• Registers both fullscreenChange and fullscreenError as simple events in DOMEventProperties.js, enabling onFullscreenChange and onFullscreenError React props
• Assigns fullscreenerror discrete event priority, matching fullscreenchange
• Adds unit tests for both events using the testNativeBubblingEvent pattern

Confidence Score: 5/5

• This PR is safe to merge — it follows established patterns for adding new DOM event support with no risk to existing functionality.
• The changes are minimal and formulaic, following the exact same pattern used by every other simple event in the React DOM event system. The naming conventions are correct (verified by tracing through registerSimpleEvents), the event priority classification is appropriate, the Flow types are complete, and unit tests are included. No existing behavior is modified.
• No files require special attention.

Important Files Changed

Filename	Overview
packages/react-dom-bindings/src/events/DOMEventNames.js	Adds 'fullscreenerror' to the DOMEventName Flow type union, correctly placed in alphabetical order alongside the existing 'fullscreenchange' entry.
packages/react-dom-bindings/src/events/DOMEventProperties.js	Adds 'fullscreenChange' and 'fullscreenError' to the simpleEventPluginEvents array, which registers the onFullscreenChange and onFullscreenError React event handlers. The camelCase naming follows the established convention and correctly maps to lowercase DOM event names via registerSimpleEvents().
packages/react-dom-bindings/src/events/ReactDOMEventListener.js	Adds 'fullscreenerror' to the discrete event priority switch case, alongside the existing 'fullscreenchange' entry. Discrete priority is appropriate for this user-initiated event.
packages/react-dom/src/tests/ReactDOMEventPropagation-test.js	Adds unit tests for both onFullscreenChange and onFullscreenError using the testNativeBubblingEvent helper. Tests correctly set bubbles: true and cancelable: false matching the actual DOM event spec.
