Does this issue still exists? Can you give me some more details?

[liayn]

Yes it does.
Simply open the BE and check your browser's console - network panel - and see the 404 response.
As denoted above, the instance runs in a subfolder of the webroot, but the CSS is included from webroot, which is wrong.

I can confirm this issue.

Actually I've another problem with it, it tries ot load:

http://domain.com/typo3/typo3conf/ext/pt_extbase/Resources/Public/CSS/Backend.css

The domain is running in the main-directory and not in a sub-directory like in the complaint of @liayn .

Like this in ext_tables.php it works:

// Custom CSS include
if (TYPO3_MODE=="BE") {
    $extRelPath = \TYPO3\CMS\Core\Utility\ExtensionManagementUtility::extRelPath('pt_extbase');
    $TBE_STYLES['inDocStyles_TBEstyle'] .= '@import "'.$extRelPath.'Resources/Public/CSS/Backend.css";';
}
