[clipboard-apis] .write() for text/html doesn't define a canonical form #233
Description
With an input
<!doctype html> <html> <head> <title>Title of the
document</title> </head> <body> <p>Hello World</p>
</body> </html>
All browsers return something different for navigator.clipboard.write([clipboardItem]);.
- FAIL Safari returns
<head> </head> <body> <p style=\"caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); font-style: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration: none;\">Hello World</p> </body> - PASS Firefox returns
<head> <title>Title of the document</title> </head> <body> <p>Hello World</p> </body> - FAIL Chrome returns
<head> <title>Title of the\n document</title> </head> <body> <p>Hello World</p> </body>
The spec currently is not mandating what should the be the serialization, which in returns makes it difficult to test:
web-platform-tests/wpt#50744
web-platform-tests/wpt@1023ea6
Even if a strict canonical form was not required.
It would be good to define what .write() means in the context of read/write operations. It is the exact copy of the data in read. is it the information visible to users (with another ambiguity about styling such as display: none element etc.)
