Bug 1992824 [wpt PR 55256] - Anchor: Update anchor-scroll-position-try-011.html to scroll more., a=testonly

Automatic update from web-platform-tests
Anchor: Update anchor-scroll-position-try-011.html to scroll more.

This patch updates anchor-scroll-position-try-011.html to use
scrollWidth and scrollHeight for scrolling to force different fallback
selection. Previously, we would prefer to use last remembered offsets
which wouldn't change things until we intersect the containing block.
