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.
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:
