Chrome Version: 71.0.3578.75 Revision 06ef00b5279f93f8e0c1e73acedd49d7dcc09767-refs/branch-heads/3578@{#836}(32/64-Bit)
OS: Windows(7,8,8.1,10),  Mac (10.13.1, 10.13.6, 10.14.2) and Linux(14.04)

Steps to reproduce:
1.Launch chrome and navigate to chrome://restart and relaunch browser to invoke remote NTP.
2.Add 2 shortcuts back to back one after another.
3.Now try to click on 'Undo' button in the toast notification message.
4.Observe.

Actual Result  : 1. Toast notification message doesn't stay for enough time after adding more that one shortcut at a time
                 2. Hence, unable to undo the last added shortcut on Remote NTP.
Expected Result: Toast notification message should stay and should be able to undo the last added shortcut on Remote NTP.

This is a regression issue, broken in 'M-70', and below is the bisect info:
Good Build:70.0.3537.0 (Revision: 587303)
Bad Build :70.0.3538.0 (Revision: 587811)

Change-Log URL: https://chromium.googlesource.com/chromium/src/+log/70.0.3537.0..70.0.3538.0?pretty=fuller&n=10000 

Suspecting:r587313?

@kristipark: Could you please check whether this is caused with respect to your change, if not please help us in assigning it to the right owner.

Note:
1. Issue is reproducible only on remote NTP.
2. Similar issue is also seen when trying to remove to shortcuts from remote NTP.
3. Providing suspect through 'Change-Log' because unable to perform bisect using 'per-revision' and 'chromium bisect' script.
4. Tried performing 'per revision' bisect on multiple Windows and Mac machines but unable to perform the same since getting errors.
5. Unable to perform 'chromium bisect' script as issue is not reproducible on chromium builds. 

Thank You!
