Prototype not clickable with '?featureset=fullscreenScaleToFit&fullscreen'

Hi,

Before with my prototypes with '?featureset=fullscreenScaleToFit&fullscreen' appended to the prototype URL, all the screen transition elements could be clicked and the prototype would transition to the next screen. Now pretty much all the screen transition elements can't be clicked and I have to exit fullscreen in order to click them. I rely on having '?featureset=fullscreenScaleToFit&fullscreen' appended to the URL to get the prototype to appear in the desired way for demo purposes. Before just setting it to '?fullscreen' gave me the desired appearance but there was a sudden change some months ago where I now had to use '?fullscreenScaleToFit&fullscreen' to get the same desired appearance. Just using '?fullscreen' now is too small. Any chance this can be addressed soon? Thanks!
