"filter" css property not working on SVG in iOS 17

I am facing an issue with the filter css property applied on SVG on recently released IOS17. The filter: invert(1) works correctly in IOS 16 and below. Validated this in both browserstack and real device as well.

The svg logo and filter css style has been there for a long time and it is working fine on all the OS and devices except for iOS 17. The filter: invert(1) css is added conditionally, based on the background of the web page. I tried adding -webkit-filter styles as well to see whether it works, but it doesn’t.

You can run this codepen containing the example for the same: https://codepen.io/rajeshprabhu879/pen/yLZBKQq

Run this is IOS17 and IOS16 (or less) and you’ll see the difference

Below is the example snippet –

</div>

CSS

.container svg {
  width: 100%;
  height: 100%;
  -webkit-filter: invert(1);
  filter: invert(1);
}

iOS 17

iOS 16

Is anybody facing the same problem with iOS 17. What changes would I need to do to make it work in iOS 17 as well (of course not breaking in previous versions as well) ?

    I think it’s a Safari bug. So you can use the CSS fill property for changing the background color of the svg instead:

    .container svg {
  width: 100%;
  height: 100%;
  fill: white;
}

    I can reproduce this problem with WebKitGTK 2.42.1 (I noticed this with GNOME Web).

    This is a known WebKit bug, see https://bugs.webkit.org/show_bug.cgi?id=261806.

    Fortunately, there is a workaround: apply the filter to the parent element of your svg instead of directly to the svg.

    In your example, the CSS would need to be:

    .container svg {
  /* Same as before */
  width: 100%;
  height: 100%;
}

/* But the filter needs to target the parent of the SVG */
.container {
  filter: invert(1);
}

    I got inspired by https://bugs.webkit.org/show_bug.cgi?id=201336, which is an older WebKit bug about how CSS filters are incorrectly not applied for some selectors.

    And as a bonus, this preserves the original correct behavior on other browsers as well.
