Does not work with Angular ShadowDom ViewEncapsulation

[marod424]

When an angular component uses ShadowDom ViewEncapsulation, ColumnCopy does not work.

https://angular.io/api/core/ViewEncapsulation#ShadowDom

I have a use case where I need to show raw email bodies in an Angular application. Those email bodies include custom styling, that often overrides application styling if ShadowDom encapsulation is not used. Unfortunately using ColumnCopy to copy data out of the email bodies has been essential for users of the application, however preserving the email style is also important to the product.

It would be great if ColumnCopy could find a way to work with Shadow DOM.
