And I remember that there is no problem when using R64, R65.

Hi,

Could you give us the content of chrome://serviceworker-internals/ at repro step 3 and after refreshing the page?

Hi bashi,
I don't know this is what you need.

Here is content at repro step 3

Sorry for mistake.
I check content once again like below.
 1) Open doc in offline mode
 2) Open chrome://service~~~ then copy the content
 3) Refresh the doc
 4) Refresh chrome://servie~~ page then copy

Thank you for the response. Looks like SW wasn't involved in this situation. Cc-ing falken@ to confirm.

I don't think we can conclude that yet.

Can testing team or someone else with Chrome OS 66 Beta repro this? My Chromebook is supposedly on Beta but it's version 65. Another Chromebook is stuck on Stable because "This setting is enforced by your administrator."

Labeling this a regression per comment 3.

+yawano: do you have ideas how to repro/debug this?

Although I guess I'm probably on Chrome Stable 66 now.

Chrome OS Files app is simply opening the URL. I don't think there is much Chrome OS specific thing here.

I'm able to open offline docs without reloading in Chrome 67 Beta.

I could not reproduce this, so WontFixing. Reopen if you still see it.
