UNSAFE_DOCUMENT_WRITE: document.write in the component

Severity	Fault	Stage
error	customer (the source package)	build output

What it means

The component calls document.write, document.writeln or document.open, which write into or replace the whole host page outside the component’s shadow root (rule document-write).

How to fix

Render inside the component with JSX; to print, open a window the component builds with DOM methods, never document.write.
