What steps will reproduce the problem?
(1) Launch chrome
(2) open different URL's in different tabs in same window & observe all the URL's open successfully
(3) Open another tab in the same window & navigate to chrome://flags
(4) Enable 'Use Views browser windows instead of Cocoa.' flag
(5) Relaunch chrome
(6) Existing tabs(step 2) are getting blank without refresh

What is the expected result?
All the existing tabs data should be displayed successfully (without refreshing the tabs) when flag is enabled.

What happens instead?
All the existing tabs data displayed as blank (without refreshing the tabs) when flag is enabled.

Screencast attached for reference.
