On the homepage https://test.archiveofourown.org a logged in user will see their most recent unread messages. The buttons on each message are, in the following order, Delete | Mark Read | Reply.
On a comment on a work page, the buttons are Reply | Thread | Delete.
For consistency, let's change the front page so that the buttons are Reply | Mark Read | Delete.
All seems to be working
Android 7.1.2, Chrome 79.0.3945.116
Inbox comment buttons are now "Reply | Mark Read | Delete".
The buttons still work as intended: "Reply" posts a reply comment, "Mark Read" removes the comment from the front page but leaves it in the Inbox, and "Delete" removes the comment from the front page and the Inbox (not from the work).
For moderated works, inbox comment buttons are now "Approve | Mark Read | Delete".
The buttons still work as intended: "Approve" makes the comment public, the other options leave the comment unapproved but gone from the front page.
