Sharing pane overwrites current owner

Did this always happen? It seems pretty big.

To Replicate:

• In the databrowser, create a new file in, say, the private folder (https://jackson.localhost:8443/private/test.txt)
• Once you do that, the private folder has two resources (https://jackson.localhost:8443/private/test.txt and https://jackson.localhost:8443/private/.acl - the private folder's default acl, seen below)

# ACL resource for the private folder
@prefix acl: <http://www.w3.org/ns/auth/acl#>.

# The owner has all permissions
<#owner>
    a acl:Authorization;
    acl:agent <https://jackson.localhost:8443/profile/card#me>;
    acl:accessTo <./>;
    acl:defaultForNew <./>;
    acl:mode acl:Read, acl:Write, acl:Control.

• At this point, everything's good. text.txt inherits its permissions from private's acl.
• Go to the sharing pane and click "Set specific sharing preferences"
• This will cause a new file (https://jackson.localhost:8443/private/test.txt.acl) to be made (see below)

@prefix : <#>.
@prefix acl: <http://www.w3.org/ns/auth/acl#>.
@prefix c: </profile/card#>.

:owner
    a acl:Authorization;
    acl:accessTo <test.txt>;
    acl:agent c:me;
    acl:mode acl:Control, acl:Read, acl:Write.

• Everything's still fine because it adds c:me to the acl.
• Now, click the green plus and the single person icon to add a new user.
• Add another webid like https://ldp.demo-ess.inrupt.com/114176645321964550648/profile/card#me
• This updates https://jackson.localhost:8443/private/test.txt.acl to be below

@prefix : <#>.
@prefix n0: <http://www.w3.org/ns/auth/acl#>.
@prefix c: <https://ldp.demo-ess.inrupt.com/114176645321964550648/profile/card#>.

:Read a n0:Authorization; n0:accessTo <test.txt>; n0:agent c:me; n0:mode n0:Read.

• Notice that instead of adding the new user, it fully replaced the original owner of the document.

Commencez par le flux du panneau de partage déclenché par « Set specific sharing preferences » et par l’ajout d’un utilisateur avec le signe plus vert. Suivez la manière dont l’ACL existante est mise à jour lorsqu’un nouveau WebID est ajouté ; c’est terminé lorsque le nouvel utilisateur est ajouté et que le propriétaire actuel ainsi que les autorisations existantes sont conservés. Reproduisez les étapes indiquées dans l’issue pour vérifier l’ACL obtenue.
