Cursor jumps to beginning of measure after entry of tie

Windows 7, GIT commit: c67a0ae

1) create new score
2) click first measure, enter Note Input mode
3) 4 E E E E +

Result: cursor jumps back to beginning of measure after pressing "+". Actually, all the way to the clef, if this is the first measure of the system. It's a display issue only - the actual cursor position is where it should be (adding more notes behaves correctly), but it's a bad one.

Seems to happen basically any time you enter a tie. You don't notice it if the tie was across the barline, because the cursor is supposed to be at the beginning of the measure anyhow. But if the tie happens to cross a system break, you get the same behavior where the cursor actually appears over the clef.
