Microsoft Bing Testing Sticky Search Bar Header

"Microsoft is testing a new search bar/box header for the Bing Search results. The Bing search bar sticks to the top as you scroll through the search results. Google just rolled that out a month or so ago and now Bing is testing it. I spotted this via Sachin Patel, who noted the line divider between the search bar and the results, which may be new. He posted about it on X - but it seems the sticky search bar is a test too."

"He posted about it on X - but it seems the sticky search bar is a test too. I can see the sticky search bar on some searches and in others, I do not see it. Here is a GIF of it in action: Here is a screenshot showing the Bing search bar stick midway down the search results: Here is what it looks like at the top, without the divider: Forum discussion at X."

Microsoft is testing a sticky search bar/header for Bing that remains fixed at the top while scrolling through search results. The test sometimes includes a line divider between the search bar and the results. The feature is visible only on some queries and appears to be rolled out as an experiment. Visual evidence includes a GIF and screenshots showing the search bar sticking midway down results and at the top without a divider. The behavior mirrors a recent Google rollout of a persistent search bar, indicating alignment of search UI patterns.
