delete_own_comment_enabled doesn't work

[phgv]

The option delete_own_comment_enabled doesn't work because the delete button is not showed.

The error is in the file comments.pt (line:113)
The condition canDelete is not necessary because there are the same conditions in the forms below.
Deleting this condition works fine to me.

Plone: 6.0a1.dev0

Hope this helps
