Input validation reset state when dirty

[colearendt]

On the error handling, after an error has occurred during deployment: The error message doesn't clear when I change things, which gives me no visual feedback if I am getting the same error or different, etc.

Ideal behavior: Error message / validation pops up... when I change the field in question, that error message should be cleared so when I try / fail again, the error re-appearing shows that my button-click did actually do something.

Reproducible example:

• publish notebook with source (ERROR because this is not supported yet)
• change the title
• try to publish again (as source)

In unrelated news - if there is a straightforward way to intentionally generate publish errors once Publish with Source is enabled, that would be helpful to testing / debugging the error handling flow! Not sure the best way to accomplish that!
