Real Time Counter can become stuck and does not count down #4893
Description
sometimes in the browsers i use for cacti, Firefox and chrome, the real time graph counter does not count down and the graph remains black. today all the chrome real time graphs were stuck. exiting the browser many times and reopening after a while solves the issue. except a random graph of thos open stays stuck.
