For some reason updates doesn't work when I switch to another tab (I simulated it by pressing debug tools).
And when I play again, I don't see new blocks

Code LGTM. @panteleymonchuk are you happy with it ?

Updating when pause now works properly.
However when we play again I see bunch of data. Does it expected behaviour?
