A bug occurs how long a policy content/remove has a language limitation. If 'initialLanguageCode' of content is the same as one of the allowed languages then the user can delete content. Because initial language code is set when content is edited in given language behavior is nondeterministic. To eliminate this bug additional "target" should be passed as an argument when the permission check I performed. After this change, if the user has content/remove policy with language limitations then he has to have access to all languages of content.

Documentation

After this change, if the user has content/remove policy with language limitations then he has to have access to all languages of content.
Below is an example of how a permission check could be achieved

$translations = $location->getContent()->getVersionInfo()->languageCodes;
$target = (new Target\Version())->deleteTranslations($translations);
$permissionResolver->canUser(
    'content', 'remove', $location->getContentInfo(), [$location, $target]
);

QA

• moving content to trash
• removing location
• removing content from trash

TODO:

• Implement feature / fix a bug.
• Implement tests.
• Fix new code according to Coding Standards ($ composer fix-cs).
• Ask for Code Review.
