FYI, this works as expected on Windows. The inforbar stays across redirect.

On Android, the issue exists in all the channels.

Hmm, it seems this affects Instant App prompt infobar too.

Make sure you have instant app enabled on the device through "Google" settings.

Change search engine in Chrome Beta (M60) to non-Google so that you won't get instant app link in SRP. e.g. use yahoo.com for testing.

Search "buzzfeed tasty" in the omnibox and click on the link for "www.buzzfeed.com > tasty" in the SRP.

You should see the infobar flash.

As this is treated as user ignore the infobar, all the following encounter of the link will always load in Chrome.

Fix instant apps banners immediately disappearing.

Compares the URL the instant app banner was launched on with the current
WebContents URL to ensure we're not mistakenly dismissing banners on the
same page they were launched.

This check occurs before we use the general InfoBar ShouldExpire(),
which was using the NavigationDetails to see if this was the same page,
which is untrue on a redirect.
