Due to some subtle interactions between used doxygen commands and the defined `\cgalAdvancedEnd` incorrect HTML code is generated.
This was shown by `xmllint (and some options) as
```
parser error : Opening and ending tag mismatch: div line</td></tr>
```
With the `\noop` "trick" this can here be overcome.
The presented output though looked OK.
Due to the change for the doxygen fix https://github.com/doxygen/doxygen/pull/7888 the file `mag_sel.png` is replaced by `mag_sel.svg`, as a result the search glass in the search box was not present anymore.
(Note this is only valid for versions 1.8.19 and newer).
When having a bit a long citation description, the description runs, in the HTML output on the bibliography page, into 3 or more lines where the 3rd and following lines continue underneath the citation number like:
```
[1] Eric Berberich, Arno Eigenwillig, Michael Hemmer, Susan Hert, Lutz Kettner, Kurt Mehlhorn, Joachim Reichel, Susanne Schmitt, Elmar Schömer, and Nicola Wolpert. Exacus: Efficient and exact
algorithms for curves and surfaces. In Gerth S. Brodal and Stefano Leonardi, editors, 13th Annual European Symposium on Algorithms (ESA 2005), volume 3669 of Lecture Notes in Computer Science,
pages 155–166, Palma de Mallorca, Spain, October 2005. European Association for Theoretical Computer Science (EATCS), Springer.
```
The example was found in e.g. https://doc.cgal.org/latest/Algebraic_foundations/citelist.html
- corrected the "overflow"
- made the citation number right aligned
When (re)generating the documentation from the sources and not using the, internally patched CGAL, doxygen version one gets messages about:
```
warning: ignoring unsupported tag 'EXTRACT_ALL_NO_DETAILED_IF_EMPTY'
```
By introducing the option `CGAL_EXTRACT_ALL_NO_DETAILED_IF_EMPTY` this doxygen setting can be steered
- option not supplied to cmake, will use as if specified `-DCGAL_EXTRACT_ALL_NO_DETAILED_IF_EMPTY=ON`
- option supplied to cmake as `-DCGAL_EXTRACT_ALL_NO_DETAILED_IF_EMPTY=ON` will write the line `EXTRACT_ALL_NO_DETAILED_IF_EMPTY = YES` in the doxygen configuration
- option supplied to cmake as `-DCGAL_EXTRACT_ALL_NO_DETAILED_IF_EMPTY=OFF` will write the line `#EXTRACT_ALL_NO_DETAILED_IF_EMPTY = NO` in the doxygen configuration, so just using the default setting of `NO` line could be omitted but it is better to have a placeholder
Currently the needed extra definitions for MathJax usage (i.e. `\newcommand` and `\def` commaonds) are distributed over the header file and in a number of source code files.
Doxygen has the possibility for a centralize this by means of the MATHJAX_CODEFILE configuration setting, this has been implemented.

Based on #3713 a number of problems were solved, but also some new issues introduced.
- BaseDoxyfile.h see to it that the CGALAdvancedBegin is in a detailed part, so be sure to terminate the brief part by an extra carriage return
- commands like \pre, \note read till the beginning of the next section but a \htmlonly is not seen as a section separator, so insert an extra carriage return
- some places missed an "Advanced" indicator, used the cgalAdvancedType here.
##Note
in Periodic_2_triangulation_2.h there appear to be a number of images that are a bit in thin air (Captions: "Insertion of a point on an edge." and "Insertion in a face."). Also just above these images theer are a number of functions that have documentation, but this is non-doxygen documentation and as such not seen by doxygen
Form the doxygen documentation:
Normally the contents between \htmlonly and \endhtmlonly is inserted as-is. When you want to insert a HTML
fragment that has block scope like a table or list which should appear outside <p>..</p>, this can lead to invalid
HTML. You can use \htmlonly[block] to make doxygen end the current paragraph and restart it after \endhtmlonly.
