TYPO3 Core

After updating to TYPO3 9.2 we have a problem when opening the viewpage-module:

#1498144052: Parameter $extensionName cannot be empty if a fully-qualified key is not specified. (More information)

InvalidArgumentException thrown in file
/home/someuser/typo3v9/web/typo3/sysext/extbase/Classes/Utility/LocalizationUtility.php in line 83.

33 TYPO3\CMS\Extbase\Utility\LocalizationUtility::translate("maximized", NULL, NULL, NULL, NULL)

In EXT:viewpage/Resources/Private/Templates/ViewModule/Show.html there is a call to f:translate of the following form:

{f:translate(key: 'maximized')}

Seems that the extension name is neither present within the f:translate call nor in the $request->getControllerExtensionName() within TranslateViewHelper.
