Deploy Azure FunctionApp container to App Service as linuxFxVersion - azure

Question

I am working on deploy isolated Azure Function App container on Azure App Service.
I have created App Service Plan:
"sku": {
"name": "P1v2",
"tier": "PremiumV2",
"size": "P1v2",
"family": "Pv2",
"capacity": 1
},
"kind": "linux",
with App Service:
"kind": "functionapp,linux,container"
I am using AzureWebAppContainer#1 task:
- task: AzureWebAppContainer#1
displayName: Deploy to app service
inputs:
azureSubscription: ${{ parameters.azureSubscription }}
appName: my-web-app0name
imageName: myacr01.azurecr.io/myregistryname:tag01
configurationSettings: -linuxFxVersion DOCKER|myacr01.azurecr.io/myregistryname:tag01"
appSettings: ${{ parameters.appSettings }}
resourceGroupName: my-resource-group
When the task is executed by Azure DevOps yaml pipeline in the logs there is info that:
Trying to update App Service Configuration settings. Data: {"appCommandLine":null,"windowsFxVersion":"DOCKER|myacr01.azurecr.io/myregistryname:tag01"}
I do not understand why the windowsFxVersion is used instead of linuxFxVersion.
On resource level in Azure Portal I can also see that I have windowsFxVersion set instead of linuxFxVersion.
Worth to mention that when you are clicking thought the wizard on Azure Portal with default Function App it is set as linuxFxVersion.
