Shadowroot / Javascript question

[Danp2]

Today a Zul user on AutoIt forum asked for support here:
https://www.autoitscript.com/forum/topic/205553-webdriver-udf-help-support-iii/?do=findComment&comment=1505239

it uses shadow roots.
I have made some analysis and I comes to sucha a nice JS

document.querySelector("body > print-preview-app").shadowRoot.querySelector("#sidebar").shadowRoot.querySelector("print-preview-button-strip").shadowRoot.querySelector("div > cr-button.action-button")

Currently I wonder if this javascript snippet

document.querySelector("body > print-preview-app").shadowRoot.querySelector("#sidebar").shadowRoot.querySelector("print-preview-button-strip").shadowRoot.querySelector("div > cr-button.action-button")

will be handy in any way ?

You can assign this to me.

@mlipok This appears related to #358. Can this one be closed?

I still wonder what you think about such JS usage in relation to using shadowRoot especially that ASAIK this is not possible with frames, especially to use JS to interact with nested frames from the main document level.

lets stick them separate.

#325 is about _WD_ElementOptionSelect usage
#353 is about JS usage

wondering if such readyState checking is possible:

document.querySelector("body > print-preview-app").shadowRoot.querySelector("#sidebar").shadowRoot.document.readyState

hm... I rethink this case and I think it was not related. But maybe I'm wrong .
