Feature Request: Delayed dump

[joanmarie]

Example use case: I had to debug an issue related to Microsoft Edge while using its Copilot AI-writing feature. I needed to see the full accessibility tree when the Copilot popup was visible. This tool would be perfect for that -- if the Copilot popup didn't vanish if focus moves outside of Edge.

There are similar cases, like wanting to see the accessibility tree of a browser's location bar / omnibox when the popup is visible, or that of the listbox associated with an ARIA combo box (e.g. to ensure the option has the correct selected state as the user arrows among items).

Proposed user experience: Add a command-line option whereby the user can specify the delay in terms of seconds.
