It's additional fix for https://github.com/vakata/jstree/issues/2431.
As <li> element has role='none' it should be hidden from assistive technologies. But this element still has accessible label (aria-labelldby) attribute.
Some assistive technologies might ignore role='none' if element has accesible name. In some cases this can cause unwanted behavior, for example:
Latest version of axe-core 4.1.0 - reports missing children.
Mozilla firefox exposes incorrect element position to screen reader.
To fix this aria-labelldby attribute cold be removed from <li> element to not confuse assistive technologies. <Li> element should be hideen from assistive technologies and no need any aria attrbutes. Our focusable element is <a> and accessible name is already exposed by this element.
