Slug validation (once working) doesn't warn user of failed save (reported on github)

If you get validation working there is another issue - failed validation on a non-active tab will (correctly) cause the page not to save, but there is no warning of this.

I would expect 1) a warning e.g. "Folder Name failed validation" and probably 2) the first tab with an error to be activated.

Cheers

Sorry, this should be on github instead - I have created an issue
