CR and LF characters ignored in textarea placeholder

[Eric4]

Hello,
In textarea placeholder, the carriage return and Line feed characters and ignored. Tested and reproduce with the latest version and a 27.x version, with an old profile and a ne created profile.

Theses characters are well interpreted in this place by Chrome, firefox, Edge, even IE 11.

On the W3C documentation, we can read this :

User agents should present this hint to the user when the element’s value is the empty string and the control is not focused (e.g., by displaying it inside a blank unfocused control). All U+000D CARRIAGE RETURN U+000A LINE FEED character pairs (CRLF) in the hint, as well as all other U+000D CARRIAGE RETURN (CR) and U+000A LINE FEED (LF) characters in the hint, must be treated as line breaks when rendering the hint.
