Random websites are not suspending

[godzfire]

Been noticing some random website tabs are not suspending, and just staying active. Two that are currently happening for me are Google Calendar (https://calendar.google.com/) and Amazon Buyer/Seller Messages (https://www.amazon.com/gp/message?ref_=ya_d_l_msg_center#!/inbox, actual url is https://www.amazon.com/messaging/ followed by a unique link I can't post).

There is no active input or anything on the page to keep them active. If I would refresh their page and then go to a different tab, they will likely then Suspend. It doesn't make sense why it's not consistent or reliable though.

Hello @godzfire
I ran a bunch of tests, and both Google Calendar and the Amazon Messages page suspended correctly at 1, 5, and 30 minutes. They also suspend manually fine, which is good.

Then, I tried using Calendar a bit, and it seems the calendar event notification is keeping the tab active. So, I'm guessing that since Google Calendar is a "live" app, it has a bunch of stuff happening in the background that keep the tab appearing as-if active.

I don't have any active messages in my Amazon inbox, so I can't test that one. But I've seen in other cases where messaging web pages do a lot of magic tricks with invisible text areas to support a rich editor for emails or messaging. It's possible that's happening here too -- but that's only a guess.

@rkodey It's not consistent with a specific site or activity. It's basically at random. I could go on and off Google Calendar a bunch of times doing stuff and it will suspend just fine, and then out of nowhere one time will just not suspend. Not doing anything specific, not in the middle of a task that would stop it from suspending, just doesn't suspend. I might have 3 github tabs open, and for some reason one randomly won't suspend, yet if I refresh it, it then will. Nothing changed, just a refresh. Tinder.com, a web forum, there's no rhyme or reason.

It doesn't happen often (<5%), but when it never used to happen with The Great Suspender and even original Marvelous Suspender, you notice.
