Not working in GridRows - no image

[otherpaco]

If used in a GridRow no image is displayed.

The image call to
/typo3conf/ext/easycaptcha/Classes/Service/Image.php?pid=30&identifier=easycaptcha-1
returns status code 500

And I can find this error message:

Core: Exception handler (WEB): Uncaught TYPO3 Exception: Unable to find a form element with the given identifier: easycaptcha-1 | ColumbusInteractive\EasyCaptcha\Exceptions\ElemenIdentifierNotFoundInForm thrown in file XYZ/public/typo3conf/ext/easycaptcha/Classes/Exceptions/ElemenIdentifierNotFoundInForm.php in line 12. Requested URL: XYZ/typo3conf/ext/easycaptcha/Classes/Service/Image.php?pid=30&identifier=easycaptcha-1

I replaced paths and domains with XYZ

If used in same form outside a GridRow everything works fine.

Typo3 10.4.6
PHP 7.4.3

I ran into a similar problem when using fieldsets. It seems to me like Image.php is only checking the first level of elements, skipping any nested ones.
