New Power BI Desktop UI and conditional ObjectEnumerateInstances

Hi people, I'm the author of a custom visual in App Source called Multi Info Cards and it seems like the users of this visual are having trouble with conditional formatting, which is in fact a problem with my ObjectEnumerateInstances.

In the visual code for the ObjectEnumerateInstances I use an if to check for a boolean value in the "Cards" menu asking if the visual will be affected by Conditional Formatting, then if it's true a new menu for Conditional Formatting appears in the pane where users can set up. When the new UI arrived, this feature has broken, however I don't think I can fix it because it would need to debug using Power BI Service, which still uses the old UI. 

So my questions are: is it a new UI bug that will be fixed? Or this will be the official behaviour and I can't make ObjectEnumerateInstances menus "hiddeable" anymore? Is there a way for me to fix it without having the access to the new UI in the service?
