            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.
