See below image, in certain conditions YouTube results are showing double, with the second result going to an identical video, but with &pp tag in the URL
The first 4 linked videos from the screenshot are:

To replicate:
Search for something, probably better with queries with fewer overall results, e.g., https://kagi.com/videos?q=nh-l12+ghost
Expect singular result for each video, preferably without any unnecessary identifiers like &pp=XXX
