&sysparm_use_polaris=false Appending to Portal Page URL

[BehelC]

Our customer has a business need to allow users to manage notification preferences on the portal. I saw that there is an existing SN widget that will work for us, sys_platform_notification_preferences. The functionality is good but we needed to customize the widget as the customer didnt want all of the default options that the widget provides so we cloned it and threw it on a portal page. 

For some reason when we load the page with the cloned widget, it keeps appending "&sysparm_use_polaris=false" to the url and it breaks the widget/locks up the page. This happens before we've made any changes so the cloned widget is exactly the same as the OOB widget, which seems to work fine. 

Also of some note, if we put both the OOB widget and the cloned widget on the page, it works fine. Every once in awhile the page with just the cloned widget will work but I cant replicate a reliable pattern for that. 

Just wondering if anyone has a similar experience or a potential fix

has context menu. I've attached the widget for context.
