Could not complete the operation due to error 800a025e

Question

What does this error mean in IE10/11:

Error: Could not complete the operation due to error 800a025e. 

And how would I debug it?

It says its this line:

this.nativeSelection.removeAllRanges();

I had this error coming up recently, I fixed it with the following chceck:

var sel = window.document.getSelection();
if (sel.rangeCount > 0 && sel.getRangeAt(0).getClientRects().length > 0) {
    sel.removeAllRanges();
}
