How to repeat:
Create a new EER Diagram. Create a table (I used the toolbal) and add a couple of fields. Create a second table and add a couple of fields as well. Double click a table - the edit table multi tab pane opens at the bottom of the windows. Now double click on the other table and then back on the first table, etc. With each double click, Workbench used (5.2.40 CE and older) to fill the multi tab pane with the double-clicked table's data. This is not the case anymore.

If you save the 2 table diagram, re-run Workbench and open the saved model, the problem persists. You can't go into edit mode by double-clicking any-table but the first one (which ever you choosed to double click it first!)
