This is currently expected as the Popup and some other components, like the Window for example have a dynamic position that is controlled via the top and left styles.
The unsafe-inline has to be used.
We understand that this not ideal, but there is no other option to dynamically set the position of an HTML element. If such an option is available we will review it and discuss an optimization.
Apologies for the inconvenience this may have caused you.
