Hint text misses newline

[puzzlewolf]

In Firefox on Android, the newlines in the hint text of the extended input field are not shown. Maybe bug in Firefox?

In chrome, the newlines are fine.

Apparently Chrome is actually in the wrong here

The placeholder attribute represents a short hint (a word or short phrase) intended to aid the user with data entry when the control has no value. A hint could be a sample value or a brief description of the expected format. The attribute, if specified, must have a value that contains no U+000A LINE FEED (LF) or U+000D CARRIAGE RETURN (CR) characters.
