I've noticed this on my Moto X Play when device is very low on power (1-3% or so). Snackbar is displayed, but pages seem to be (need to confirm this) loading properly. Data is available (wifi and/or cell). Snackbar disappears once device is charging and exists battery saving mode.

Tested this on an older Samsung device running 4.3, and I can't reproduce this behaviour.

Flagging this for triage. Offline browsing is now enabled for the whole population, so it would be good to fix up these edge cases.

[triage] doubt this may relate to Android OS design/phone manufaturer's implementation about power saving mode/connectivity, we would like to see if this still happens in an newer OS/device  

Hi Inoana:

Would you help check if this issue can be repro. with the latest Google device (so w/ the native Android OS)? Thanks.

Grisha - can you reproduce this still on your Moto x Play?

I don't have that device anymore, unfortunately - but at the time the issue was consistently reproducible and I don't believe this code changed since... So likely it still is.

I'll try to reproduce this on a Galacxy S6, which I do have handy, and will report back.

Hi Ioana,Grisha

I've tried the scenario mentioned above on a Samsung S6 EDGE (Android 7.0) with power at 3%, 5% and 1% and could not reproduce the snackbar trigger. 
Please note that I've tried it with battery saving on and after repeated tries the same result could be observed: the pages opened correctly with no snackbar trigger.  

This was tested on 59.0b3, 58.0(build 2)
