Steps to reproduce:
Go to https://www.online-timer.net and set a timer. The timer pauses frequently (usually a few seconds after switching to another tab). This also occurs in Safari, but to a lesser extent (the pause isn't as immediate). This occurs in compatability mode as well. It seems to run fine if you stay on the website.
On Safari, there is a request for notifications, which does not appear in Orion.
That the timer should run normally in the background.
