THPDFHTMLImporter.OnDiagnostic

Event raised for every diagnostic produced during an import run

property OnDiagnostic: THPDFHTMLDiagnosticEvent read FOnDiagnostic
  write FOnDiagnostic;

The unit is HPDFHTMLImport; the handler receives the same THPDFHTMLDiagnostic record that gets appended to Diagnostics

The event keeps firing after the retention list reaches MaxDiagnostics, so live logging remains complete

With StrictCSS switched on the event fires before the EHPDFHTMLUnsupportedCSS exception propagates
