Issue with menu type Tagged items, J.5.2

Hello,

I am not sure if this is the correct way to ask your attention for this issue.

Over a year ago I posted an issue called "Issue with menu type Tagged items, J.4.4.1", see https://issues.joomla.org/tracker/joomla-cms/42529

Although some people agreed that this issue should be solved in the Joomla core, it was solved with a patch on the file components/com_tags/src/Service/Router.php, made by @RickR2H. However, no changes were made to the core. I have been using the patch since then and I am very happy to have it. When there is a J.4 update I always check this file for changes and I make sure that I keep the patched part.

Now I want to upgrade the site to J.5 and I see that the issue is still present in J.5. Oher people have noticed this as well. I do not dare to copy the patch code to J.5 because the file components/com_tags/src/Service/Router.php has changed in J.5. and this is beyond my knowledge.

My questions:

Is there someone who has the knowledge (and is willing) to make this patch J.5 compatible?
Or, even better, would it be possible to make these changes part of the J.5 core code?

For details, please check my original J.4 issue at https://issues.joomla.org/tracker/joomla-cms/42529

Kind regards, Frits
