Bug #35948	Foreign Key Reference Column taking 20-30 seconds to populate

Description:
When creating a foreign key on the foreign key tab of the table editor, when I click on the table's column to select the reference column, the reference column drop-down refreshes about 30 times, taking about 20 seconds to complete.

It seems to work correctly afterwards.

The problem increases as more tables are added to the model.

How to repeat:
Start creating a bunch of tables, and create foriegn keys for them.  As more and more tables are added, the drop-down list starts to repeatedly refresh itself.  When I had about 15 tables, I counted it refresh 21 times.

Thank you for the bug report. I could not repeat with a model project with 17
tables. Could you please provide the output of Help->System Info like the
showed below?. Thanks in advance.

As a follow-up.  For an unrelated reason, I shut down WorkBench and restarted it.  The first foreign key I tried to create thereafter populated the drop-down once.  The next one refreshed 6 times.  Interestingly enough, the very next one refreshed 3 times.  So, it doesn't seem to matter so much how many tables, as it may be related to how many times in a single running session one creates a foreign key.  

Here is my system information:
