<code> tag have stopped working on wiki.qt.io. Has to use <syntaxhighlight lang="cpp-qt">

It seems that the syntaxhighlight configuration in the wiki software has changed so that the '<code>' tag no longer defaults to <syntaxhighlight lang="cpp-qt">. (see Wiki Editing Hints - 9. Code highlighting)

This affects a lot of pages on wiki.qt.io where the <code> tag has been used, mangling the formatting of these pages.

One has to now explicitly use the <syntaxhighlight lang="cpp-qt"> tag to make it work again.
<code lang="Some lang"> does not work either. '<code>' is just interpreted as a normal html code tag apparently.

Example:
From How to Use QSettings (Old revision with <code>):

<code>
#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>
...
class MainWindow : public QMainWindow
{
 Q_OBJECT
public:
...
</code>

See attached screenshot "How to Use QSettings - Old revision using code.jpg" for resulting browser display. (Note how the formatting is mangled.)
Does not syntaxhighlight as promised on Wiki Editing Hints - 9. Code highlighting

...
    The wiki uses the standard GeSHi syntax highlighter.
    The only customisation made, has been to add the <code>
    tag to the highlighted list handled by GeSHi. The default
    language is set to C++/Qt toolkit. You can change the 
    language with the lang="" attribute.
...

If you change the tag '<code>' to '<syntaxhighlight lang="cpp-qt">' it works as expected.
From How to Use QSettings (New revision, edit by me, using <syntaxhighlight lang="cpp-qt">):

<syntaxhighlight lang="cpp-qt">
#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>
...
class MainWindow : public QMainWindow
{
 Q_OBJECT
public:
...
</syntaxhighlight>
