• OS Version: Windows 11

Steps to Reproduce:

1. open query editor
2. connect to data source
3. script 2 ad hoc queries, e.g., select top 10 * from sys.tables (repeat on next line)
4. turn on Actual Plan
5. execute both queries in same batch
6. under QUERY RESULTS pane, select Properties icon from first query sidebar of Query Plan tab
7. observe Properties table is truncated on the bottom by subsequent second query plan section
   -- no sizability options available to vertically widen first query section
   -- no vertical scroll bar available on Properties table to see truncated properties (e.g., QueryTimeStats)
