Higher CPU usage after resuming from suspend on Mac?

Hi,

I've noticed that Zulip doesn't seem to be "idling" properly after resuming from suspend on Mac -- background CPU usage goes from near-zero to ~10% and never recovers until quitting the app.

@axfelix the most likely possibility is that you have the open open to a view that contains animated GIFs in the message feed or animated GIF custom emoji (E.g. in a user status in the sidebar); animated GIFs burn CPU by continuously animating.

https://github.com/zulip/zulip/issues/19732 and https://github.com/zulip/zulip/issues/14489 are relevant if that's indeed the situation.
