Click events not detected when viewing kineticJS based websites

I have written an application in Electron running on Linux which rotates through an array of URL addresses displaying various web pages from building automation systems. It appears that the servers on some of the automation systems are using the KineticJS framework in their web pages. I am unable to detect mouse click events when the mouse is clicked anywhere in the page where the KineticJS framework is used. It looks like the web page is creating an iFrame effect. On other systems that do not utilize the KineticJS frame work, I am able to click on a text input field and force an on-screen keyboard to be displayed based on the click detection and verifying that the target is an input field of type text or number.

I have tried using the standard mouse click event listeners, but can’t figure out how to grab the event from the container.

Here is a screen shot showing the HTML of the page that defines the container (https://i.stack.imgur.com/0irvd.png)

This is an image of the actual page (https://i.stack.imgur.com/JpYmT.jpg)

If I click in the blue bar to the left or the grey area at the top or bottom of the page, the mouse click event comes through no problem, however if I click anywhere else, the click events appear to be blocked.
