Workflow fails because of missing toast message title

In the last step of a workflow (End user interactions), a toast message is enabled by default. According to the interface, the message itself must be provided, title can be empty.

My workflow failed to complete multiple times because I didn’t provide a title. Error Message:

“Toast message title must be provided when toast message is enabled.”

While I understand that workflows are being disabled after several failed execution attempts, in my opinion it’s unnecessary to do so because of such a minor issue. Maybe the workflow could trigger a warning message instead?
