Unable to interact with light DOM children in browser using polyfill

[Artur-]

Meta -

OS: macOS High Sierra 10.13.2
Selenium Version:
3.8.1
Browser:
Works on Chrome+Safari which have native Shadow DOM support
Broken in IE11, Edge, Firefox

Expected Behavior -

• You can interact with an element which is in light DOM only, regardless of if the browser supports native shadow DOM or not.
• An element returned from executeScript can be used in a subsequent call instead of always throwing StaleElementReferenceException

Actual Behavior -

An element which is in light DOM only can be returned by executeScript but trying to perform any action on the element results in StaleElementReferenceException

Steps to reproduce -

git clone https://github.com/Artur-/shadydom-selenium
cd shadydom-selenium
mvn install

I presume this is about how the webdrivers detect that an element is attached to the DOM, and that either the polyfill does not implement all the needed methods or the webdrivers do not use the polyfilled methods.
