moveToTrash fails to remove a symlink to a directory after trashing

My bash steps

mkdir ~/myFolder
ln -s ~/myFolder ~/mySymlink
cd ~/mySymlink
touch 1 2 3

My Qt code

qDebug() << QFile::moveToTrash("/home/user/mySymlink/");
true

And I open Trash and see mySymlink, looks good but /home/user/mySymlink/ also alive! So moveToTrash doesn't do move to trash action, it do copy to trash action. To make move to trash action I should do Qt code without symbol / at the and

qDebug() << QFile::moveToTrash("/home/user/mySymlink");
true

Yes, in this case the mySymlink is really removed. It looks like not a bug but feature. If you think that this is feature then I suggest to describe this behavior in docs.

P.S. For folder it is no matter does you use / at the end or not so QFile::moveToTrash("/home/user/myFolder/") is the same as QFile::moveToTrash("/home/user/myFolder");

P.P.S. But if you use QFile::moveToTrash("/home/user/myFolder/../Folder2") then I expect big problem...
