Workflow definition id not found when workflow name contains spaces

When using the run workflow activity and using the following Liquid syntax, the parent workflow does not find the child workflow when the name contains spaces.

`{{ "Child with space" | workflow_definition_id: "name" }}`

Should there be restrictions on the name field in the UI to not allow spaces or any other characters that are not allowed? When publishing a workflow, is there anything that verifies the workflow for things like this?
