When specifiying <ContainerImageName> periods are being substituted for dashes

According to the documentation the allows periods and the process doesn't error when they are present, however when the container image is built it substitutes (Normalizes) the periods for dashes. In the container image name I would like to prefix with our Azure container registry.

Would this be possible to do? I can work around by creating another build step to tag after build, but hoping to not have to.

Thanks.

No file or test is named in the issue. Start by reproducing a container build with periods in ContainerImageName and trace the image-name normalization in the build tooling. Done means periods remain valid in the resulting image tag, including when the name is prefixed with an Azure container registry.
