Printing from inside of the custom WebComponent with Shadow DOM attached missing Shadow DOM stored styles

[nikita-kliushnikov-idt]

It may happen that you render your app as a custom WebComponent and use Shadow DOM (attach your styles in Shadow DOM for isolation purposes).
Printing using react-to-print from the inside of such custom WebComponent results in styles (ones stored in Shadow DOM) missing.

It would be great to traverse styles from the contentRef up to the document using getRootNode() (polyfill may be needed) instead of simple selecting styles on the document level.
