[Bug]: Copying table by copyTable() and deleting it spit errors

[fw]

Describe the Bug

Calling the copyTable() function, I got the error: java.lang.NullPointerException: Cannot invoke "java.lang.Boolean.booleanValue()" because "this.visible" is null.
But that duplicating is complete and can be used usually.

After calling the copyTable() twice, and deleting a copied table on the "Tables", the deleting is successful but I got the "Warning" dialog contained below:

java.lang.NullPointerException: Cannot invoke "java.lang.Boolean.booleanValue()" because "this.visible" is null

To Reproduce

1. Add tables by "Add Default Tables" from the menubar.
2. Run the macro [h: copyTable("D20", "X")] at the chat.
3. Getting error message below.

java.lang.NullPointerException: Cannot invoke "java.lang.Boolean.booleanValue()" because "this.visible" is null error executing expression copyTable("D20", "X").
Error trace : chat

4. Then, run the macro [h: copyTable("D10", "Y")].
5. Delete the duplicated table "Y" at the "Tables" UI （using the ⛔ button）.
6. Getting the "Warning" dialog.

Expected Behaviour

Getting no error.

Screenshots

No response

Additional Context

• Deleting another copied table is successful without errors.
• Using the macro function deleteTable at the deleting action, also spit similar errors to the chat window: java.lang.NullPointerException: Cannot invoke "java.lang.Boolean.booleanValue()" because "this.visible" is null error executing expression deleteTable("X")..

In another story, after creating a table by createTable and copying by copyTable, deleting the former table show a "Warning" dialog.

1. Run the macro [h: createTable("X",1,1)][h: copyTable("X","Y")] at the chat.
2. Deleting "X" table (not "Y") at the "Tables" UI.
