### Reviewers

Sharad was fixing a showstopper today that looks similar to this. For his case, the ```EditWindow``` is a popup window that is not part of the main Dynamo visual tree. Which led ```WPF.FindUpVisualTree``` to not finding ```DynamoView``` and crashes. If ```PackageManagerPublishView``` is not part of the main visual tree, then it might have the same issue. Just thought I'd highlight this.
