Change Details

After talking to @phuedx, now that IntersectionObserver is widely available in our grade A browsers, we recommend deprecating the mediawiki.viewport library. Intersection/MutationObserver will be more performant than our existing approach in RelatedArticles and QuickSurveys. We will update RelatedArticles and QuickSurveys as part of T262859 to use Intersection/MutationObserver . For browsers that don't support it we will not show related articles and will not log impressions for QuickSurveys, which is fine. We will then deprecate this module in core. # TODO [x] Drop from MobileFrontend [ ] Rewrite QuickSurveys to use MutationObserver [ ] Rewrite RelatedArticles to use MutationObserver [] Deprecate in core
