Hi,
after opening a PMR with IBM about this issue it was concluded that if the project is built with the RBD 9.5 EGL RUI Libraries (dojo mobile widgets library 1.3.0 or later) then the problem is resolved but partially.
Under Chrome browser on iOS or Android the application works as expected - that is responding correctly and timely to click events on dojo mobile widgets. However, the problem still exists at Safari Browser(iOS 9.3.4).
