POE2 - Respec is buggy when changing branches to reach the same nodes

I've recorded a demonstration of the bug here: https://www.youtube.com/watch?v=Uh2SMJJRRpU

Attempt 1:
1) Temporarily removed nodes to gain points to spend.
2) Spent the points building the alternate branch.
3) Removed nodes from the old branch.
4) Re-added the nodes from step 1.
5) Click Apply -> Nothing happens.

Attempt 2:
Same as the first attempt, but I click Apply after step 3. This time it works, except that the removed nodes from the old branch have come back. I've now ended up with both branches being filled out.

I've been able to respec again after this to successfully remove the old branch, but this shouldn't be necessary.
