IW is not visually marked as unsaved

Testing #186196 on Linux

In the last step, the IW prompts for a save before the editor exits. However, unlike normal files (or custom editors), its tab is not visually marked as being "unsaved". If it quacks like an unsaved file, should it look like an unsaved file?

this is by design - scratchpads are never marked dirty. You also don't get a prompt when closing the tab manually for the same reason
