Google is testing another feature for “people also search for,” this one overlays entity information in a popup menu when you hover your mouse over the term. This was spotted by Valentin Pletzer who called this “refinement bubbles within entity popover.”

I tried to replicate this but I cannot – so it must be some sort of test.
Reminds me a bit like the overlays in featured snippets – but I like this implementation of it way more because it is separate and not injecting anything within the specific content from that publisher.
