> @smfr, thanks for the comment. Interestingly, due to a bug in Chrome, that example already works. I believe the `z-index:0` isn’t properly creating a stacking context. However, in the general case, can you please give more information about **why** you want that example to work? I.e. by moving one div tag, you could make it work in either case. What **can’t** you do, if backdrop-filter respects isolation?

I'm not sure what you mean by "by moving one div tag". As a web author, I should not have to rejigger which elements on my page create stacking context in order to get the effect that everything behind my element with the backdrop gets filtered, and in fact that may not be possible (maybe my isolation ancestor is transformed, but I also want backdrop filter to include non-transformed elements).
