ID 510861 - Pane tabs are still shown when the Viewer tab is active after restoring a workspace from startup with Show Pane disabled

Problem summary
Pane tabs are still shown when the Viewer tab is active after restoring a workspace from startup with Show Pane disabled.
 
Customer reported version
nuke.13.1v2
 
Customer reported platform
windows10
 
Steps to reproduce
1) In Nuke, right-click the Pane with the Viewer tab.
2) Select Show Tabs to disable it.
3) Select the Workspace menu item and save a new workspace.
4) Open the Preferences... > Startup and choose the startup workspace for the newly saved one.
5) Close and reopen Nuke and observe the pane with the active Viewer tab.
 

 
 
Expected behavior
The pane tabs should remain hidden when loading a previously saved workspace at startup with the 'Show tabs' knob disabled.
 
Actual behavior
The tabs are displayed and the 'Show tabs' knob is re-enabled after starting up with a workspace where 'Show tabs' was disabled with a Viewer tab present. However, this only occurs during startup and not when just reloading a saved workspace.
 
Workaround
There is no available workaround at this time.
