Chrome version : 70.0.3535.4 (Official Build) 94e3d408570fcf39b8718d8d1637e978e11803bc-refs/branch-heads/3535@{#6}(32/64-bit) 
OS :Win(7,8,8.1,10) ,Mac(10.12.6 , 10.13.1 , 10.13.6, 10.14) and Linux(14.04 LTS)  OS

Pre-condition: Enable "Enable using the Google local NTP" ,"New Tab Page Background Selection" and "New Tab Page Custom Links" flags under chrome://flags.

Steps to reproduce:
1. Launch chrome and open NTP.
2. Click on 'Add Shortcut' icon and add anew shortcut to NTP.
3. Observe that a confirmation message of 'Shortcut added' along with 'Undo' and 'Restore default shortcuts' buttons is seen.
4. Wait for the confirmation message to go away.
5. Press tab till focus reaches 'Add shortcut' icon now press tab again , press enter and observe

Actual Result  :Able to navigate to 'Undo' or 'Restore default shortcuts' buttons even when confirmation message is not seen.
Expected Result:Should not be able to navigate to 'Undo' or 'Restore default shortcuts' when confirmation message is not seen ,instead focus should travel directly from 'Add shortcut' icon to gear icon.
