Owner-reported regressions in Firefox + Safari on desktop after the
initial F8-09 patch landed:
1. The TOC trigger rode up with the page during scroll instead of
staying pinned to the viewport (mobile worked, desktop did not).
2. Clicking a popover item scrolled the matching section so its
heading went up under the chrome — only the table body was visible.
Root cause for (1): the in-game shell declares `overflow-y: auto`
on `.active-view-host` so mobile (where `.game-shell` is fixed at
`inset: 0`) has an internal scroll region. On desktop the host
grows with content, no overflow ever engages, and the document
body becomes the actual scroll container. Per CSS spec the host
remains the "scrollport" for any `position: sticky` descendant, so
the trigger inside the report column never sees the scroll event
and rides up with the body content.
Fix:
- Swap the trigger from `position: sticky` to `position: fixed`.
The component is mounted only while the report active view is on
screen, so the fixed element is naturally tied to the view's
lifetime. Anchor at `top: 4rem` (below the in-game header), and
on `min-width: 1024px` shift `right` by 18 rem to clear the
always-on sidebar; below 1024 px the sidebar is an overlay so
the default `right: 1.25rem` matches the report's right padding.
- Add `padding-top: 4.5rem` to `.report-view` (4rem mobile) so the
first section heading does not land under the trigger at scroll
position 0.
- Add `scroll-margin-top: 7.5rem` to every `<section
id="report-…">` so `scrollIntoView({ block: "start" })` lands
the heading below the trigger after a popover-driven jump.
- Sync `ui/docs/report-view.md` §"Table of contents and active
highlight" with the new positioning rationale.
Tests: `pnpm check`, `pnpm test` (821), `pnpm test:e2e
report-sections` (4 projects) all green.
