(apigatewayv2): VpcLink subnet selection ignored

[ronaldslc]

new apiGateway.VpcLink(stack, 'VpcLink', {
   vpc: props.vpc,
   vpcLinkName: 'VpcLink',
   subnets: []
})

would result in all VPC subnets being added

  VpcLink66988216:
    Type: AWS::ApiGatewayV2::VpcLink
    Properties:
      Name: VpcLink
      SubnetIds:
        - Ref: XXXSubnet1SubnetC63F3793
        - Ref: XXXSubnet2SubnetB84D1BD7
        - Ref: XXXSubnet3Subnet6C7F7A39
      SecurityGroupIds: []

while

new apiGateway.VpcLink(stack, 'VpcLink', {
   vpc: props.vpc,
   vpcLinkName: 'VpcLink',
   subnets: [subnet2, subnet3]
})

would result in all VPC subnets being added PLUS the extras repeated

    Properties:
      Name: VpcLink
