Linkhandler doesn't build links when using registerPageTSConfigFile
we're trying to provide a news Linkhandler like in this tutorial: https://usetypo3.com/linkhandler.html
But when we're inserting the tsconfig by using the following script in `Configuration/TCA/Overrides/pages.php`:
'Linkhandler configuration for News (TYPO3 8.7)'
..the link in frontend isn't rendered. The news-link in backend is selectable in RTE and everything else works fine.
When we paste the content of the `Configuration/PageTS/Linkhandler/tx_news_news_typo3-8.typoscript` directly into the tsconfig field of our root page, the link is rendered in frontend.
So, it seems that `registerPageTSConfigFile` doesn't provide always the contained ts config.
