TYPO3 Core

Tried to override metatags from page settings in a plugin on this page.
Failed on og:image, always both, the page og_image and the image from my plugin are rendered, even if $replace = true is set.

TYPO3 Versions 10 & 11

lines 117 and 150 in TYPO3\CMS\Core\MetaTag\AbstractMetaTagManager
The code does not allow to replace metatags with "allowMultipleOccurrences" set

if ($replace === true) {
    $this->removeProperty($property, $type);
    $this->properties[$property][] = ['content' => $content, 'subProperties' => $subPropertiesArray];
    return;
}

if (isset($this->handledProperties[$property]['allowMultipleOccurrences']) &&
    (bool)$this->handledProperties[$property]['allowMultipleOccurrences']
) {
    $this->properties[$property][] = ['content' => $content, 'subProperties' => $subPropertiesArray];
}
