Unreal Engine 4 pointer cursor stuck on web browser widget

I know UE4's web browser widget is an "experimental" feature, but this is a pretty obnoxious bug that they have refused to fix for at least 4 years.

As far as I can tell, as soon as your cursor enters the "pointer" state while inside the browser widget, it will be stuck there indefinitely, even after you close the widget. The only solution I have found is to prevent it from ever reaching that state.

If you have full control over the webpage you are displaying, you can modify your CSS to use some other cursor type for all your elements. I did not.

My solution? Set the cursor for every element to 'default' using javascript.

var nodes = document.querySelectorAll('*');

for(var i=0; i<nodes.length; i++) {

    nodes[i].setAttribute('style', 'cursor:default !important'); 

}

When? All of the time.

It does seem excessive to do every element every tick, and it probably is, but when you have no control over a webpage, you never know when some new pesky element is going to be shoved into the DOM and screw you again. Why risk it?

One thing I did try was to set a software "Hand" cursor. I assume this translates to cursor:pointer, but who knows? That did nothing at all. Maybe the bug here is that there is no "pointer" cursor type in UE4, so the web browser widget has no idea how to turn it off.

One thing I did NOT try was to set up invisible hardware cursor images. Perhaps there is a conflict in the transition from hardware to software cursors? I do not know, but I do know that I end up with both when I mouse out of an HTML button. Forever.
