Here the comment field is being overwritten - IF for whatever reason the user had a value there it would now be lost if the error would get raised below, because the value would not get reverted.

Which could throw meaningful info from the scene away if the user used that comment field.

What ACTUALLY happens even is that the "expression" that is being set:

tool["Comments"].SetExpression("self.Input.OriginalWidth")

Will now persist after the validation and suddenly the user has an expression on the comment field that they don't know about or shouldn't have.

Basically we're altering the user's scene in a way without taking care that it's reverted, which we shouldn't be doing.

We should be doing this through a context manager so that whatever happens, the original state gets reverted - even on the error.

BUT, even better - I'd argue that if the ACTUAL issue is that it errors on having no input connections that we explicitly capture that case - so that if for whatever other reason the resolution can't be computed we still get an error (if e.g. the node network evaluates with errors, or there's a memory overflow issue, etc.
