This looks like a ConfirmInfoBar at least from the visuals.  Any reason we can't
use that?

[Changwan Ryu, 2014/10/14 04:04:40]

The main reason for deviating from ConfirmInfoBar is as follows:
1) We need to use bold style and in-text link to meet the design requirement
from the original bug.
This cannot be handled by message text of ConfirmInfoBar.
2) The link should launch an intent instead of opening a new tab.
