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

	<Left>netstandard2.0/System.ComponentModel.Composition.dll</Left>
	<Right>right</Right>
	</Suppression>

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:

runtime/src/libraries/System.ComponentModel.Composition/src/TypeForwards.cs

Line 4 in b1908e2

[assembly: System.Runtime.CompilerServices.TypeForwardedTo(destination: typeof(System.Lazy<,>))]

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.
