Investigate System.Lazy<,> type not found when comparing netstandard2.0 against NetCoreAppCurrent #106628

The "right" entry means that the type couldn't be found on the right side (NetCoreAppCurrent). We should investigate why.

It should have a typeforward for this: https://github.com/dotnet/runtime/blob/b1908e291f8b3c48572507419be0f0b5c9f5c9f6/src/libraries/System.ComponentModel.Composition/src/TypeForwards.cs#L4

I double checked that the preview 7 package has this typeforward for all target frameworks. netstandard2.0 version points to netstandard, net*.0 points to System.Runtime. Seems to me like this might be either an APIcompat bug, or we're not giving all the references for comparison.
