I think we can remove this DCHECK now. It is taken care in the next line inside
is[HTML|SVG]ScriptElement functions.

Removed in https://codereview.chromium.org/1943403005/. Thanks.
Done.

+    DCHECK(isHTMLScriptElement(newCurrentScript) || isSVGScriptElement(newCurrentScript));
     m_currentScriptStack.append(newCurrentScript);
