Infinite loop when inserting Array into RBTree

[nk327]

Somewhat of an edge case, but can lead to a bad state in applications using this library -- hanging and high CPU usage.

Repro case:

let rbtree = new RBTree(function(a, b) { return a.value - b.value; });
rbtree.insert( [ ] );
rbtree.insert( [ ] );  // <-- infinite loop

This works ok with BinTree though.

Found in package version 1.0.1

I can confirm this bug is still present in v1.0.2.
The obvious workaround is to create a child class of RBTree and override the insert method with a check Array.isArray(item) == true and abort.

Are there any plans/suggestions for an official fix?
