When I went to this question some of the text was highlighted in yellow. Is there something wrong with this?
Quoting his amazing answer:
The highlight is a Google search feature, where it’ll show the matching section on the page by adding a specially formatted URL hash fragment (starting with
:~:text=). You got to that page by clicking on a featured snippet at the top of a Google search result and are using Chrome. Google rolled out the feature worldwide this week after testing it in limited settings for a while.
This is not a Stack Overflow feature, and the feature is not limited to just Stack Overflow search results. This is Google’s search engine hooking into Google’s browser (and any other browser that supports Google's proposed scroll-to-text fragment specification).
Stack Overflow could choose to disable the feature, either by adding a
Document-Policy: force-load-at-topHTTP header (which disables all fragment scrolling, including linking to answers and comments), or by disabling featured snippet support entirely. Both options look to me to have too broad an effect, and don't think they would be good options.
TL;DR: This isn't specific to Stack Overflow (or any site on Stack Exchange's network,) it's your browser. As a result, this isn't a bug.
