           Summary: [S60] font's face attibute is converted into font-face
                    declaration incorrectly
           Product: WebKit
           Version: 412
          Platform: S60 Hardware
        OS/Version: S60 3rd edition
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: New Bugs
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: lauri.taipale at digia.com


Reproducible with WebKit versions 413 and 525 on the S60 platform.

If HTML "font" element's "face" attribute contains a font name that has
"independent" numbers in it, e.g. "Font 123 Sans", the font name is converted
into CSS "font-family" declaration incorrectly which causes the font name
parsing to fail and WebKit to fall back to the default rendering font.

When the "face" attribute's value is converted into "font-family" declaration,
font names that have spaces in the name are not properly enclosed in quotes
(').

E.g.

    <font face="Font 123 Sans">

becomes

    font-family: Series 60 Sans;

when it should be (according to the CSS specs)

    font-family: 'Series 60 Sans';

This causes the "CSSParser::ParseFontFamily" method to stop parsing the font
name when it encounters the number part of the font name (in this case "123"),
causing the font name to be truncated, i.e. "Font 123 Sans" becomes "Font".
This then causes the CTextRenderer(Factory) to fall back to the default
rendering font (debugged with WebKit 413).

(If the font name in the "face" attribute is enclosed in quotes (against the
HTML specification), e.g. <font face="'Font 123 Sans'">, then the conversion
and parsing is done "correctly".)
