Parent class tagged values deleted from child class

[RichB]

Using EA version 14 on Oracle repository with security and user locks enabled.

Problem observed:
I locked a class that specializes a parent class that has tagged values assigned.  The parent class was not locked by any user.
 In the tagged values pane, I select a tagged value under the parent and clicked the red X to delete the tagged value.  The tagged value is removed from the tagged values pane.
Clicking on the (locked) parent class the tagged value is not longer associated with the parent class.

Steps to reproduce:
1 - create a class called parent
2 - assign a tagged value to the class
3 - release the user lock on the parent class
4 - create a class called child
5 - Create a link of type 'Generalization' from child to parent
6 - observe the parent class tagged values appear in the tagged values pane for the child class
7 - select the tagged value and click delete
8- observe the tagged value is removed from the child class's tagged value pane
9 - select the parent class
10- observe the tagged value does not appear in the parent's tagged value pane

Expected behavior:
I would expect that a user that has a lock on the child class can add/modify tagged value notes for tagged values associated with the parent class (existing behavior and working) but would be unable to delete tagged values from the parent without explicitly unlocking the parent and performing the delete operation while the parent is the active object.
