Unable to add customer facing comment without transitioning issue

As an agent, I am unable to add a comment without transitioning the issue to Waiting For Customer. If I wish to add a comment without changing the status I must add the comment and then transition the issue back to Waiting For Support.

• These transitions generate unnecessary emails to customers. The customer receives three emails because I added a single comment.

Use case example: I would like to provide an update to my customer saying that I am still working on their issue. I would like the issue to remain in Waiting for Support status.
