Describe the bug

Edit attributes refresh not updating/reverting values

To Reproduce

Steps to reproduce the behavior:

1. Go to USS tree view and enter a filter search, locating a file to view Attributes
2. Right-click on file and select Edit Attributes
3. Change some values but do not apply, instead click the refresh
4. See attributes not updated/reverted after refresh

Expected behavior

In this scenario, I would assume the refresh would work similar to cancel updating the webview back to the original values.
