What steps will reproduce the problem?
(1) Load m.entertain.naver.com
(2) After page load finished, select an article.
(3) After page load is finished, start typing amazon.com in URL bar
(4) After page load finished, press back key or back button from the window
(5) Observe Forward button state is toggling for few duration (It's state is toggling between enable and disable during the transition)

What is the expected result?
There should be only one state change, Continuous toggling should not happen

What happens instead?
Continuous toggling is happening, hence it's observing as flickering.

Additional Info: canGoForward() API is returning true for sometimes, and false for sometimes until state is gets stable at true state.
Navigation entry count and last committed entry index is coming same during the issue scenario. Issue is observed only in this scenario, other scenario, it works well.
