(codepipeline): Stack.crossRegionReferences fails with "aliasName: required but missing."

[closesimple-wl]

Describe the bug

I understand crossRegionReferences is experimental, but I'd expect to actually get it deployed.

The problem seems related to the CrossRegionSupportStack. The most relevant part of the stack trace looks like:

aws-cdk-lib/aws-kms/lib/kms.generated.js:1:2998)
    at CfnAlias.renderProperties

Expected Behavior

No error when using cross-region CodePipeline action.

Current Behavior

Error: Resolution error: Supplied properties not correct for "CfnAliasProps"
  aliasName: required but missing.

Trace: Error: Resolution error: Supplied properties not correct for "CfnAliasProps"
  aliasName: required but missing.

Could you provide minimal reproduction code please? I'm not sure how you have this setup in CDK

[closesimple-wl]

Minimal-ish reproduction repo: https://github.com/closesimple-wl/codepipeline-repro

[closesimple-wl]

I realize the reproduction repo's code isn't the correct approach because I need a separate stack for the other region's resource(s). But even after stripping it down to direct cdk synthesize on a single App with two Stack, the error message is the same.

So regardless of the example code not being correct according to

aws-cdk/packages/aws-cdk-lib/README.md

Line 228 in af998c8

You can enable the Stack property `crossRegionReferences`

, this still appears to be a real bug.

Is there any workaround for this problem?
