Joel - P1 regression, PTAL :) We can merge back a fix if its straightforward.

You can do a bisect using git bisect, I put notes in:

I have bisected and found the CL that caused this change is https://chromium-review.googlesource.com/c/chromium/src/+/878327

Batalov, jam@, juliatuttle@, do you have any suggestions on how to fix the cros FileManager?

It looks to be the code at https://cs.chromium.org/chromium/src/chrome/renderer/net/net_error_helper_core.cc?l=888&rcl=b0b7031e882448d2f7db62641926c0ff2ad55445 where previously a reload of the page would cause drive to load the offline page, and now the page is not reloaded.

fixed email address for Vladislav.

Does anyone have any thoughts on how to fix FileManager / drive offline?  Could we revert the patch as a start?

Looking at the official build bots for M66, I see red.  Seems patches submitted to the M66 before #19 are the cause.  Waiting for that redness to be cleared by the M66 release managers ... kaibai.

Fix for #20 landed,  crbug.com/828963#c18 

M66 Beta builders are now green, closing fixed.  Joel to verify fixed if that's ok.
