We used to query and save all non-zero `scrollTop`/`scrollLeft` to restore the page perfectly. However, this became very slow with Chromium v100 regression (see issue).
This change only queries and stores `scrollTop`/`scrollLeft` for elements that are ancestors of the action target. The resulting snapshot does not perfectly recreate the original screen, but should be good enough to inspect the action.
