ECS task definition ephemaralStorage overrides do not work

[InterMeta]

While providing Infrastructure overrides with a deployment, ephemeralStorage parameter in task definition does not add configuration or overrides existing configuration on AWS ECS task definition.

{
"ephemeralStorage": {
"sizeInGiB" : 100
}
}

Expectation / Proposal

ephemaralStorage parameter will be added or overridden in ECS task definition.

Traceback / Example

ephemaralStorage setting works fine if ECS job definition is created manually and storage is specified as part of configuration.
