TYPO3 Core

TYPO3 8.7.20

After adding this code over Configuration/TCA/Overrides/pages.php to register my own page TSconfig:

\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::registerPageTSConfigFile(
'user_boilerplate',
'Configuration/TSconfig/page.tsconfig',
'Boilerplate Settings'
);

If the content of the file Configuration/TSconfig/page.tsconfig uses relative paths like this:

<INCLUDE_TYPOSCRIPT: source="DIR:./Page" extensions="tsconfig">

Then the TSconfig is not loaded in backend.

I've always used relative paths to include TypoScript.

If I change the content to an absolute path:

<INCLUDE_TYPOSCRIPT: source="DIR:EXT:user_boilerplate/Configuration/TSconfig/Page" extensions="tsconfig">

then the TSconfig is loaded.

Can anyone confirm this behaviour and fix that if it proceeds?
