Header-toggle-control in wrong place for reminders

Description

When a reminder of a message is triggered, that message appears in the inbox with an additional header, the send-reminders-header. This header causes the header-toggle-control element to appear in the wrong place, i.e., it appears in the header, while it should be in front of the sender’s name.

This can be solved in css with:

.send-reminders-header ~ .header-toggle-control {
    top: 57px !important;
}
