When exploring the different nodes, the tree "hides and opens"

[facundobatista]

There's an annoying visual effect.

Say I have a tree with three nodes. I'm seeing the tree.

If I click on other node, the text changes, yes, but the tree "hides" (expanding the text space) and then immediately "opens" again (making the text space smaller).

Switching between nodes shouldn't hide and close the tree...

Thanks!
