NVDA has a bug where anchor links that point to a parent element don't work correctly in browse mode — the cursor stays at the bottom of the page instead of jumping to the target. This affects both Chrome and Firefox, but not JAWS or VoiceOver. The root cause is that NVDA skips scroll events when the caret is already within the scroll target container. The workaround is to move anchor links (like 'back to top') outside their target element rather than nesting them inside it.
