This feature will make the <details> element automatically expand in response to other features which want to scroll to text or elements inside their collapsed content.
This feature will allow scroll to text links and element fragment links to become capable of targeting content inside of collapsed details elements by making the browser open them before scrolling to the desired content.
It will also allow find-in-page to search through content inside collapsed details elements by expanding them before find-in-page scrolls to them, effectively making much more content in existing webpages searchable.

Interoperability and Compatibility
If this isn't implemented by other browsers, then it will mean find-in-page is a little less powerful in other browsers, and links to content inside <details> won't work in other browsers if the <details> is closed on page load.
find-in-page can't be tested in WPT right now, but the functionality for element fragments and scroll to text fragments will be tested in WPT.
