Bug ID: 244982
Summary: css-pseudo: ::placeholder should not support
'writing-mode', 'direction', and 'text-orientation'
Product: WebKit
Version: WebKit Nightly Build
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: CSS
Assignee: webkit-unassigned at lists.webkit.org
Reporter: zlip.792 at gmail.com
It is to align Webkit with Web-Spec:
https://drafts.csswg.org/css-pseudo-4/#placeholder-pseudo
> All properties that apply to the ::first-line pseudo-element also apply to the ::placeholder pseudo-element.
and
https://drafts.csswg.org/css-pseudo-4/#first-line-styling
> User agents may apply other properties as well except for the following excluded properties:
> * writing-mode
> * direction
> * text-orientation
Current Safari Technology Preview 153 behavior is not aligned with Blink / Chromium, Gecko / Firefox and Web-Spec.
