I have the same problem with other components.

InputMask don't work at all when using Shadow Dom

https://stackblitz.com/edit/a6k78r?file=src%2Fapp%2Fdemo%2Finput-mask-basic-demo.ts

We have the same issue when using shadow dom and tooltips.

In the tooltip code 'bindScrollListener' uses 'getScrollableParents' further down which throws the error as soon as the first param is 'document -fragment'
