Code inside 12.9.issue - 12.9.0.15

In Editor I try to put following anonymous block

declare
v_variable table_name

after providing

declare
v_variable tabl

I press Ctrol <.> to get list of objects - works fine.

Then

declare
v_variable table_name.

I get another Ctrl<.> to get list o columns to declare column_type variable - Empty list is displayed.

I’m unable to reproduce this one. Is the cancel button on the toolbar enabled when the list is empty? If so it might not have the data required to populate.
