[JENKINS-69969] usernamePassword binding not setting variables correctly on Windows container

When using the following in a declarative pipeline:

 

withCredentials([usernamePassword(credentialsId: 'nuget', usernameVariable: 'NUGET_USERNAME', passwordVariable: 'NUGET_PASSWORD')])

{
  set
}
 
The NUGET_USERNAME is not being set at all, but the NUGET_PASSWORD is incorrectly having the set NUGET_USERNAME command appended, as follows:
 
{code:java}

NUGET_PASSWORD=****set NUGET_USERNAME=nuget

 

This looks like it is missing a new line between the two operations.
