Cannot add solid.community webID to an inrupt.net Chat access control list ACL

I am on inrupt.net. I can add other inrupt.net webIDs to both my Profile and into the access control (ACL) of my chat, using drag and drop. I can also add solid.community webIDs to my Profile, also using drag and drop. But when I try to drag and drop a solid.community webID into the ACL of my chat, the person does not add. The solid.community webID disappears once I let go of my mouse button.

I can see solid.community webIDs in my Profile with no issues.

まず、チャット ACL に solid.community webID をドラッグ＆ドロップするフローを再現し、次に同じ ID を Profile に追加する場合、および inrupt.net webID の場合と比較します。solid.community webID がドロップ後も ACL に残り、正常に追加できれば完了です。
