Working with shadow-dom elements in mink

[uuf6429]

It seems that stock mink functionality does handle shadow-root? I haven't found anyone asking for this use case so far.

I'm wondering if we can do this through on top of the findElement() API or so? The main complication is that we typically build XPaths and call selenium/driver API with it, while assuming we're in the correct context whereas (as I understand), shadow-dom is a different context (the shadow dom root / host).

what do you mean by "does not handle shadow root" ?

Sorry, was quite late. Say for example there is an element with id="test" in shadow DOM, it cannot be simply targeted with a #test CSS selector. I know the theory behind shadow dom, but it's my first time seeing it in practice, so I'm still digging into the details.

This could also be something to consider: https://developer.mozilla.org/en-US/docs/Web/API/Web_components/Using_shadow_DOM#element.shadowroot_and_the_mode_option

And for some inspiration / how others are doing it, this looks like a good overview: https://stackoverflow.com/questions/55761810/how-to-automate-shadow-dom-elements-using-selenium

Looking at the way the Selenium API looks like for ShadowRoot (and as well the DOM spec), we cannot add support for it in the current Mink architecture where elements are identified as an XPath, from which Mink can build new XPath queries to continue selecting.
A shadow root is isolated from the DOM tree (that's its goal) and requires an explicit reference to it to be able to start querying (separately) inside it.

Supporting this will require a full rewrite of the Mink internal architecture (changing entirely the way the driver API looks like)

That's what I was afraid of :/
