This is the console output from the latest build (3079).
I open a file, click around 5 or 6 times (all different lines) then hit the jump back (which works), then every time I hit jump forward, it shows “Already at the newest position” in the panel beneath the console in the lower left. In the log, every call to “jump_forward” results in “Already at the newest position”, no call to it ever moves the caret.
