2. Go to host configuration, click Macros tab
3. Open inherited macros tab
4. Choose one macro and click "Change"
5. See that macro remained disabled, value and description fields became editable.
6. Add new value and/or description, save form.
7. Open host configuration again, open Macros tab
8. See that edited macro presents in Host macros tab and is editable - Expected
9. Open inherited macros tab, edited macro presents in Host macros tab and also is editable - Expected
10. Click Remove
