TYPO3 Core

System: Windows
Browser: Chrome Version 92.0.4515.159

Steps to reproduce:

• Add a content with type textmedia to the page
• Add a media file (without dimensions in the fileObject)
• In Media Adjustments section set width and height
• Save
• View Page

Additional comments:

• width and height are correctly saved on BE
• you can see those values in the tt_content table as well

Actual result:

• On FE: the iframe containing the media is generated without the width attribute.
• On core: in the TYPO3\CMS\Fluid\ViewHelpers\MediaViewHelper class, $this->arguments['width'] is set to 0.0 but $this->arguments['height'] is correctly set.
• On core it seems that TYPO3\CMS\Frontend\DataProcessing\GalleryProcessor takes rather the fileObject width in consideration instead of the imagewidth parameter coming from the tt_content entry. As there is no such data in the Media file, the width result comes thus with a zero value

Thanks for the time taken reading this request.
