Multi-select of objects (e.g. tables, procedures, etc.) are not allowed some times in the Show De (4282866)

In the Show Details Panel of the DB Navigator, I can select multiple objects (e.g. several tables) and then right click to perform some operation on the select objects. With certain patterns of multiple selection, whenI right click, it un-selects all the chosen objects and only selects the row where the cursor is on.

One pattern is the following with the Table node
1. Open the Show Details Panel for the Table node
2. From the top chose the first row for the table object shown
3. Select every other row untilI have only 4 tables selected
4. Right click on any of the chosen tables and the other chosen tables will not be highlighted anymore andI see only one row highlighted

Another pattern is the following.
1. Start from any table object and select 4 consecutive tables with the initial table included
2. Skip one row of a table and select the next row
4.I have a total of 5 rows of tables selected
5. Now right click on any of the select rows and I see the other chosen tables disappear

There maybe more selection patterns causing this behavior.
