A click on the close-cross of a calendarevent will propagate?

It seems like clicks on the close cross (upper right corner) of a calendarevent will propagate to the rest of the DOM.
Maybe I am just doing something incorrectly.

Is it an intended behavior?

Problem solved by adding "return false" to the first click handler in the function _mouseEditable in kendo.scheduler.dayview.js (beside e.preventDefault).
