DisplayObject cursor property not working in CEF

Hi,

I just updated an old version of pixi.js we had been using. 

The cursor used to change to "pointer" when hovering over a DisplayObject in our embedded chromium browser (CEF).

After v4.4.0 the cursor does not change on hover.

I pinpointed that the last version it was working with our embedded browser was v4.3.5. Does anyone know why this might be and what I can do to fix it? 

Thank you
