backdrop-filter() gets ignored

[kaiserkiwi]

Use case: description, code

If I want to have a blurred background for years now I can use backdrop-filter: blur(10px). But this is not reflected in the output of dom-to-image.

Here is my jsfiddle
It has nothing to do if it's applied via pseudo classes or with negative z-index. That just done because it's less code.

filter: blur(10px) works as expected, but has a different output and is not really comparable to backdrop-filter.

Expected behavior

backdrop-filter should be applied to the output image

Actual behavior (stack traces, console logs etc)

backdrop-filter doesn't get applied to the output image

Library version
