Hi. Does it fixed?

In fact, it is not a Webix bug - sorry for misguiding you.

However, Webix catches mouse events with one document object, while the iframe contains another - it is the expected behaviour.
As a solution, you need to track the mousemoveevent in the nested iframe as follows:

Not a practical solution when dealing with same-origin policy iframes. Have a case that the iframe has Same-Origin protection and is not possible to get mousemove event from it.
