Set-AzDataFactoryV2Pipeline ignores additionalColumns

[abbgrade]

Description

Hello, I use Set-AzDataFactoryV2Pipeline for deployment automation.
Some pipelines contain copy activities with JsonSource and additionalColumns.
Manually deploying still works as expected but using Set-AzDataFactoryV2Pipeline and the DefinitionFile parameter, deploys the pipelines without additionalColumns.
It worked in the past, but not longer.
I executed Update-Module Az.* before my latest test.

Issue script & Debug output

Set-AzDataFactoryV2Pipeline -DefinitionFile MyPipeline.json
