Added ContentHeightPreferenceKey to track the total ScrollView content height.
The bug: Progress was calculated using only webViewHeight - containerHeight,
which ignores the header, title, and other content above the webview.
The fix: Use total content height (header + title + webview + archive section)
instead of just webViewHeight for accurate progress calculation.
Changes:
- Added ContentHeightPreferenceKey preference key
- Added contentHeight state variable
- Added background GeometryReader to VStack to measure total content height
- Changed progress calculation: contentHeight - containerHeight (not webViewHeight)
Applied to both BookmarkDetailLegacyView and BookmarkDetailView2.
