<pre> needs background-color and the syntax-highlighter checked

Description (last modified by )
Wiki text inside three curly brackets {{{is delivered as <code>if no line break</code> or as
<pre>when the brackets start the line.</pre>
This variant allows syntax-highlighting with Wiki Processors.
<code> is since #15910 well displayed within the limits of the Help Browser.
<pre> has two issues:
- The formatting of the area lacks of a background-color (and a border, if possible). The area should look the same as in a normal web browser.
- The result of the
#!shsyntax-highlighter is wrong, i.e.- the line break after comment lines gets lost and
- the colour for highlighted words gets lost too.
See the screenshot, especcially the orange coloured marks for missing line breaks:

Replying to Hb---:
- the line break after comment lines gets lost and
I think Java behaviour is correct here. The line break is not inside the <pre> but inside a nested <span>. It might be a Trac bug.

TracSyntaxColoring deliveres CSS like <span ...>code line <0A linefeed here></span> . Probably the Java HTML Viewer cannot display a span as block element. But all other browsers can do this.
Probably even Pygments is to blame.

I believe that is Java HTML viewer's issue. How about adding the following for workaround (untested)?
div.code pre span { white-space: pre }

It doesn't work. Swing CSS capabilities are very limited. Let's see if the next Trac update solves our problem.
Replying to Hb---:
This point will be impossible to fix. Swing does not provide colour syntaxing highlight for programming languagesIt should possible by CSS :)
