Broken links on generated documentation #7127
Description
Browsing the doxygen documentation of L4Re (https://l4re.org/doc/) I noticed that the link for the documentation of some C++ classes in the search bar is broken. For example, while searching for 'Task', two results come out in the search bar. Clicking on the first takes the user to the C interface, while clicking on the second result takes no effect.
I suspect this may be related to the fact that the name 'Task' is used to name two interfaces (one in C, one in C++), but I also noticed that both interfaces for Factory are both named 'Factory', and there the links for each individual interface work as expected.
Looking into the HTML code of the page in the Chrome DevTools, I noticed that when searching for 'Factory' (which is the case where the link actually works), if I click over the link in the result panel in the search bar, it updates the SRChildren element adding the attribute:
style="display: block;"
This does not happen when I search for 'Task'. Two results appear, but only one of the links has an effect when clicked on. I also noticed that if I manually edit the content of the page in Chrome DevTools by adding
style="display: block;"
to
<div class="SRChildren" classname="SRChildren">
then it expands the sub-menu and shows the link for the Task class documentation.
Looking at the source codes for both classes (Factory/Task), I could not spot anything that was able to justify this behaviour. I wonder if this is a bug in Doxygen, or may it be some configuration missing on the source code of L4Re which is causing the link to be broken.
Link for the sources (Task C/C++ and Factory C/C++) are given here:
Task C++ Interface

I've tried compile the documentation myself with two versions of Doxygen: 1.8.13 and 1.8.15 (the latest), but I saw no difference with respect to the broken link.
