If you would like to debug the FAB Workbench preview, follow these steps.

Instructions

With FAB running, execute the program IEChooser.exe - it should be in C:\Windows\SysWOW64\F12\IEChooser.exe
You then choose the target to Debug. If you haven’t got any other windows open, there will only be one target to choose from, either way, it should be called FAB
Note: once the IEChooser is running, you can right-click on the preview window and choose Refresh and you should see the app loading in IEChooser. Then you can do all the normal debugging that is available for IE.
