Selected element is not reported if the selected element is not part of the a11y snapshot

[natorion]

Description of the bug

Selected elements are ommited if they are not relevant for interacting with the page.

Reproduction

Repro:

1.) Open page that has a lot of divs and a few controls
2.) Select one of the divs in DevTools
3.) Reference in your prompt the selected element
4.) take_snapshot does not include the div

Expectation

a selected element should always be added to take_snapshot - no matter what type it is.

Extra checklist

• I want to provide a PR to fix this bug

Have you tried requesting verbose snapshots?

Have you tried requesting verbose snapshots?

It works with that. A human would not know that, and an AI agent does not know either. So two options:

• Add the selected element always
• returns a verbose snapshot always when an element is selected (token intensive)

Add the selected element always

this would not be doable right now since filtering is on the puppeteer side.

returns a verbose snapshot always when an element is selected (token intensive)

This can be done.

Thanks for providing the feedback.

Can we filter it down to the non-verbose screenshot afterwards before passing it on to the LLM?

Code architecture would not allow to re-use the exact same code right now. Definitely possible but a larger change. Do you prefer this option? The other option is possible right now (next days).

Another option could be to use verbose by default? In general, for styling debugging we need to rework the snapshots to be a mix of DOM and a11y but that requires some thinking.
