And then you get weird behavior for your trouble. When deleting a disk, my second click got me a 404 toast after the first click succeeded. When deleting an instance, it seemed to keep me on the same page with a 404 rather than landing on project instance list like it's supposed to.
Easy fix is to disable the button. Even better would be to give the button a loading spinner to show something is happening, which is the reason I clicked twice in the first place. Should be easy, I think Button has a loading prop.
