TYPO3 Core

On a TYPO3 9.5.4 installation we observed the behaviour that on multiple forms the property "elementClassAttribute" of a field got inherited to all following fields of the same type (Text).

On a (mostly) blank 9.5.4 installation I could reproduce this behaviour with the attached example, but this time only the "fluidAdditionalAttributes" placeholder & autocomplete got inherited and not the "elementClassAttribute".

What's important, this only happens on the first page load after cache clearing.

• Copy example file into form_definitions folder
• Add form plugin to some page and choose the "Inherit test" example
• Clear cache with "Flush all caches"
• Open page with the form in the frontend
• Some properties should become inherited from textfield "website" to "name"
• After a reload of the page it works as expected
