Can't scroll vertically

[osa1]

When I enable "event labels" using view menu, all the HECs are not fitting in my screen, but vertical scrollbar is not allowing me to scroll down to see other HECs.

Example: Here I have all 8 HECs listed:

Here, I enabled "event labels" and I no longer have all the HECs on the screen, but I can't scroll either. (see the scrollbar)

I can reproduce. Moreover, when I enable, e.g., Instant Events from the Traces tab and afterwards disable it, then I can scroll (a workaround for now). Somehow adding the event labels doesn't trigger recomputation of scrollbars, unlike adding other things.
