A user reported this issue and I was able to recreate it. You open a jira project, select any board, then open any issue type. When the issue is open right mouse click on the issue ID and open in a new tab.
The board that appears in the left tab is not the same board as you were previously in. Moreover, its the same board repeatedly and you have no way (tried new browser, clearing cache, etc.) to have that board not appear.
Is this the default behavior? How did that default board get set and why are users unable to control which one it should be. Its like Jira software is associating the board to a user id?
