Floorplan issue with popups

Hi,

i’m currently starting to setup some pages in openhab 3 and run into a small issue with a Floorplan Page.
i setup a Marker for a light which should open an popup for a dimmer.

so far so good. however as soon as i click on the marker the dimmer is not fully showin in the popup.
What could cause this ?

dimmer widget:
