I'm using Chrome (vs Cloud SDK / command line) to repeatedly replace a file in a bucket. Dragging / dropping a file to overwrite the existing one, and / or deleting it first and putting it back (changed). 

At a certain point the file stops updating and remains in a persistent state, even if I literally rm -r its parent folder.

i.e., I could have `/bucket/css/file.css` and rm -r `/bucket/css` and the file will still be available to the public.
