Merge - https://chromium.googlesource.com/chromium/src.git/+/68c32d4e9fe24e25e672095253e0f0b2e709ecf4%5E%21/

It is to align Webkit behavior 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.

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

* Source/WebCore/css/html.css - Updated ::placeholder to add 'direction', 'text-orientation' and 'writing-mode'
