bug: Can't change the current in folderTree

[mortalYoung]

Describe the bug

I want to change the current in folderTree. So I use molecule.folderTree.setActive() to change the current active treeNode. But only state changed, the page doesn't re-render.

Versions

• OS: MacOS
• Browser: Firefox
• Molecule: 0.9.0-beta.4.2

To reproduce

• molecule.folderTree.setActive()

Expected

After using molecule.folderTree.setActive(1), and the treeNode whose id is 1 will highlight.

Actually happening

The treeNode whose is 1 didn't highlight.
