Are these notifications coming from an extension or a website?

Calendar is clearly a website. Hangouts is an app (which I believe is a WebContents in its own window?)

The report doesn't say, but I'm guessing this is with the new notifications (black background), as opposed to the old (white background)?

If it is the former, then this is because Xi's fix is not in Canary yet.

No, this is with white background

Then it's still the old notification. Did you turn on the flag: chrome://flags/#enable-native-notifications, Gab?

I just saw this too with Tampermonkey desktop notification for updates - could click X to close but clicking actual notification now does nothing.  This happened once before so does appear to be regression issue.

67.0.3377.0

@#8: nope, no special flags, just Canary on corp.

@#10: This feature is still behind a flag -- chrome://flags/#enable-native-notifications, so you need to turn it on. We are still working on all kinds of surveys which are required for launch.

@#11: what do you mean by "This happened once ..."? Can you provide more information please?

@#10: you mean it's expected that the feature not behind flag is broken..?

@#12: For the old notification feature on Windows (not behind flag), peter@ or finnur@ should have better answers than I do.

Thanks for confirming, Gabriel. It seems like there's a regression in the old-style notifications and we need to get to the bottom of it. I'm more versed in the new-style notifications, but there's a chance our changes there broke the old-style notifications. I'll take a look. 

Essentially, to repro, I should be able to create a meeting in Google Calendar on my test account, wait for the reminder to pop up and click it, right? Does it repro consistently for you, Gabriel?

Yes, repros 100% with desktop notifications from all sources (hangouts might be easier for a repro?).

Removing Xi, since this is not part of native notifications.

Regression range is:

This CL looks like a very promising candidate...

Adding committer + reviewer to the thread.

Seems we have to return true from OnMousePressed/Dragged also from MessageView. I'll fix it.

Fix notification click.

In https://crrev.com/c/962556, MessageView started to use
OnMouseReleased for detecting notification click. OnMouseReleased
requires OnMousePressed and OnMouseDragged to return true in order to
receive events. However, they are only overridden in NotificationViewMD,
thus NotificationView's click event is broken.

The Regression CL initially landed in 67.0.3376.0 so no need to merge.

Thanks for the quick turnaround!

Able to reproduce this issue on Windows 10 on the reported version 67.0.3377.0 and the issue is fixed on the latest Canary 67.0.3382.0.

On clicking on the Hangouts desktop notification, getting redirected to the Hangouts Chat window.
Attached is the screen cast for reference.

Hence adding TE verified labels as the fix is working as intended.

Thanks..
