Description

Right now there's no way for a page to override the scroll anchoring heuristics, which seems unfortunate, since that means it's unreliable.

Maybe we should consider adding an overflow-anchor: always to force anchoring to happen regardless of the style changes that happen in the scroll container.

Research direction

The issue concerns the CSS Scroll Anchoring module and proposes an overflow-anchor: always opt-in. Start by reading the module's existing anchoring suppression heuristics, then determine the required specification behavior and interactions with overflow-anchor; the issue provides no file or test entry point, so completion would require an agreed design and CSS Working Group resolution.
