Link sharing broken with enforced password protection

[juliushaertl]

Steps to reproduce

1. In Settings/Sharing, enable 'Enforce password protection'
2. Try to share a file or folder as a link
3. No popovermenu accessible

cc @nextcloud/sharing @nextcloud/javascript

Likely caused by the new popover menu introduced in #10218

Found when checking for #10461
