What steps will reproduce the problem?
(1)Sign in to user -> logout -> sign in to another user -> Go to Uber tray -> click on user I'd and select 'Sign in to another user...' option
for Multiple sign-in
(2)In  Multiple sign-in screen observe delay is seen to display 'User' and 'Add an account to multiple sign-in....' message (Please refer video)

Expected: Delay should not be seen to display 'User' and 'Add an account to multiple sign-in....' message i.e. after on clicking 'Sign in to another user...' option  Multiple sign-in screen should display immediately with 'User' and 'Add an account to multiple sign-in....' message

Actual: Instead delay is seen i.e.  on clicking 'Sign in to another user...' option Multiple sign-in screen is seen with 'Shut down' and 'Cancel' option first and then after few seconds  'User' and 'Add an account to multiple sign-in....' message is seen  

This is Regression issue as same is working fine in  64.0.3282.14/10176.7.0 dev-channel Kip
