Hi there, It seems as though a number of the new mouse force touch events do not fire when inside an iframe. The only one that does seem to fire is webkitmouseforcewillbegin. The other events do not fire when attached to the element publishing the event - or to a higher handler such as window. Here is the Github issue that originally got me investigating this: https://github.com/atlassian/react-beautiful-dnd/issues/62 Examples - Example within an iframe (events do not fire) https://react-beautiful-dnd.netlify.com/?selectedKind=single%20vertical%20list&selectedStory=simple%20example&full=0&down=1&left=1&panelRight=0&downPanel=storybook%2Factions%2Factions-panel - Example outside of an iframe (events do fire) https://react-beautiful-dnd.netlify.com/iframe.html?
