Upgrading from 13.1.1 to 13.2.1 breaks <f:link.action>

Hi,

I have a custom Extbase extension, similar to the popular EXT:news.
In the list template I use <f:link.action> to call the detail action of my news controller and get to the detail page of an item.

<f:link.action
    action="detail"
    pluginName="NewsDetail"
    arguments="{slug: article.slug}"
    pageUid="{detailPageId}"
>
    ...
</f:link.action>

After updating from 13.1.1 to 13.2.1, this doesn’t work anymore.
I can still access the articles by manually going to the article detail URL (/news/d/my-article-slug), but hovering over the link I can see that the URL parameters are not getting resolved correctly.

The route enhancers are set up correctly, proven by the fact that I can still access the detail pages manually.

Reverting back to 13.1.1 solves the issue.

I’m guessing this is a bug?
