What is the new prerenderer implementation for <link rel=prerender> instead of NoStatePrefetch ?

[HotCakeX]

Microsoft Edge Version 89.0.726.0 (Official build) canary (64-bit)

 this new flag:

Prerender2

Enables the new prerenderer implementation for <link rel=prerender> instead of NoStatePrefetch. – Mac, Windows

#enable-prerender2

I'm curious to know what the new prerenderer implementation is that replaces NoStatePrefetch?

couldn't find any information about it in here

https://developers.google.com/web/updates/2018/07/nostate-prefetch

also, in the same link, it says

"Fetch the first result in Google Search results"

does prefetch/prerender in Edge Fetch the first result in Bing search results?

#enable-prerender2 = memory leak.

That's only a temporary bug with that flag, it should prerender resources differently than before :)
