Bug: “Send hyperlinks here” interferes with “Mark read” on reading plan

When clicking “Mark read” at the end of a day in a reading plan, it goes to the first reading for the next day, however if there is a second copy of the bible open with “Send hyperlinks here” this link is sent there. This is different from the other navigation links in the reading plan visual filter where clicking between different readings on the same day stays in the current pane (ignores the send hyperlinks here).

Software version: 4.0b Beta 3.
