Chat customer Idle Timeout is not accurate causing some times the timeout not fired after the set time in chat button.

Currently, the Chasitor Idle Timeout works by using a series of 1-second delays after a warning to update the timer on the screen and check if the chat should time out. However, this method often results in inaccurate idle timeout times. The time from when the warning is triggered to when the timeout actually happens is about twice as long as it's supposed to be.

Even though this approach hasn't been changed for a long time, it seems the performance is degraded as browsers evolve. It appears that there is additional processing for the computer with each delay, and this becomes a significant issue when the web browser is not in focus.

Because of these issues, the idle timeout occasionally fails to work correctly in chat transcripts.
