These fields are accessed by other tools such as parcel (for resolving local asset URLs). As per 257efdd the behavior with (at least) parcel for relative paths in sub-directries changed. Prior to that commit (last release 3.12.2) assets were resolved relative to the less module that contains the `url(..)`. From release 3.13.0 parcel resolves assets relative to the root less module, because no `currentFileInfo` is available. This is caused by tree nodes setting their prototype to an instance of `Node`. This leaves the `self` reference in `Node`s constructor pointing to the prototype, not the actual instance the data is set on. Replacing this with properties defined on `Node`s prototype fixes this.

Makes sense, have you tested with Less 4 to see if it has this issue? |
Yes, I actually discovered this in 4.1.1, verified it's also on master, then traced it back to 3.13.0. This patch works for master, didn't test any older releases. But if you like to fix this in another 3.x release I'm happy to backport it. |

Sounds good, thanks! |
