THPDFHTMLImporter.MaxDOMNodes
Upper bound on the number of DOM nodes accepted by a single HTML5 import run
property MaxDOMNodes: Integer read FMaxDOMNodes write FMaxDOMNodes;
The unit is HPDFHTMLImport; the default is 100000 nodes
Exceeding the bound during RenderHTML5 raises EHPDFHTMLImportBudget so that untrusted markup cannot drive unbounded parsing
The limit goes together with MaxCSSRules and MaxLayoutOperations, which bound the cascade and layout phases
