Query Plan Viewer does not show dependent access node's source queries in query plan

In a dependent join situation, the query plan shows the source query for the dependent feeder node, but does not show the source query for the dependent "access" or "wait" node. This is not consistent behavior. see screenshot.

By accessing the "wait" node's properties, the source query can be found. However, if the source query is long, it will be truncated, and there is no way to view the entire query if it is displayed in this properties window only (due to another bug).
