Bug ID: 182816
Summary: `@supports (display: contents)` feature query in CSS
incorrectly passes
Product: WebKit
Version: Safari 11
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: CSS
Assignee: webkit-unassigned at lists.webkit.org
Reporter: rhys at rpowell.me
If I write the following in a CSS stylesheet:
@supports (display: contents) {
display: contents;
}
WebKit will incorrectly claim to support `display: contents` and apply the styles inside that `@supports` block. As WebKit doesn't actually support this property, and instead falls back to `display: inline` which breaks many layouts dependent on `display: contents`, this feature query should not pass.
