MARKLESS_EVENT_SPREAD_UNSUPPORTED
Event handlers cannot be spread onto an element: a Markless compiler error.
Error from the compiler, while it builds your .tsrx files.
What happened
Markless prints the message, the reason, and a suggestion:
MARKLESS_EVENT_SPREAD_UNSUPPORTED: {...<spreadSource>} spreads <listed> onto an element. Events compile to static view records, so handlers inside a spread would be discarded.
The compiler owns event discovery so the browser can resume without scanning markup; a runtime spread hides which events exist from the compiler.
Write event props directly, for example <input onClick={handlers.onClick} onInput={handlers.onInput} />, and keep spreads for plain static attributes.Words in angle brackets change from case to case.
How to fix it
Start with the suggestion in the message above.
