Refresh ui-node

Hey guys,
@Steve-Mcl and myself have a very annoying issue with our contextmenu node.
Summarized:

  1. you click on a clickable shape in our new SVG node
  2. an output message is being send (incl. X/Y coordinates) to our contextmenu node
  3. the contextmenu node displays a menu at the location (specified in the input message)
  4. you click somewhere else in the dashboard, so the context menu disappears
  5. you deploy something.
  6. now suddenly the last input message is received again, so we display the contextmenu AGAIN....

Does anybody have a tip to avoid the last input message being repeated?
We have played with the storeFrontEndInputAsState value but that doesn't help :woozy_face:
