<linkName>, <linkSnippet>, and <linkDescription> of the KML <NetworkLinkControl> are not refreshed in the Data window
Only the initial <NetworkLink> <name>, <Snippet>, and <description> are displayed.
Note that the NetworkLinkControl items are correctly refreshed in the data itself. For example, when the network link is clicked in the Data window, we can see that the description is updated.
And if the network link is right-clicked and saved from the Data window, we can see the updated information in the KMZ file.
However, none of it is refreshed in the ArcGIS Earth Data window.
