If a form action is inactive, or you do not have the security privileges to access the form, then the action appears as normal. In previous application versions, there was a different appearance to indicate that you could not click the action. However, with the new UI and change to the action view type on a form, this is no longer the case. It is therefore very misleading to a user that they are meant to click on the action, which will result in customer support tickets.
There is an issue with the font weight of actions. If the section navigation is not active, then the system sets the font weight to normal. Moving forward, the section action, if rendered as a button, will appear as not active when the action is inactive.
