Steps to reproduce the problem:
[Preconditions]
1. Nexus device
2. WiFi AP
3. Make Nexus and WiFi AP connected via WiFi at least once (Auto connection: ON)

Steps]
1. WiFi AP: OFF and make sure that Nexus is in the coverage area of LTE 
2. By Nexus, download file with WEB Browser
(Execute below steps while downloading file)
3. WiFi AP: ON 
4. Make sure that Nexus is connected to WiFi AP and downloading continues
5. Wait for some time

What is the expected behavior?
Even after connecting to WiFi AP, downloading file should continue. 

What went wrong?
After connected to WiFi, the screen saying "Downloading..." changes to "Downloading pending."
Then, downloading does not start again automatically.
If "Resume downloading" is pressed, downloading will start again using WiFi. If WiFi is disabled downloading starts again
