onSelect only called once when allowMultiSelect set to true

[andreirawan97]

Describe the bug Just like the title, the onSelect prop only called once when allowMultiSelect set to true. While when set to false, the onSelect prop can call multiple times. I'm developing a double click node feature where it needs the onSelect prop to called multiple times.

To Reproduce Steps to reproduce the behavior:

1. Set allowMultiSelect to true or just leave it as default
2. Multiple clicks on a node
3. onSelect only called once.

Expected behavior onSelect called multiple times
