Summary of the change:

fade effect has a bug when fast click on buttons like Delete

I have tested this PR. Thanks for pointing out this issue.

But I found some undesired behaviors like:

• Delete button is visible when corresponding config is not set, but confirm button will not be visible.
• It feel unrelated to disable fade effect, just to fix deleting issue.

So I fixed this issue by disabling confirm button for deletion, and this PR will be closed.
Still thanks for this PR.
