-split With \G Stops After First Split

Steps to reproduce

"ABCDEFGH" -split '(?<=\G..)(?=..)'

Expected behavior

In PS 7.0.3 and earlier, this is the output:

AB
CD
EF
GH

Actual behavior

In PS 7.1.0, this is the output:

AB
CDEFGH

Workaround

This works in PS 7.1.0:

[regex]::Matches("ABCDEFGH", "..") | % Value

The fix is not documented to be in .NET 5.0.1 as of this writing, but my repro test went from red to green with the installation of .NET 5.0.1. So, looks like upstream is fixed.
