Trello delayed loading of JavaScript stuff

Trello

I’m not 100% sure, but there seems to be some kind of delay happening on Trello pages. When I don’t have the Trello tab open it makes my computer very slow and never loads, but when I’m looking at it directly it loads quickly.

What exactly happens?

Can it somehow cause issues with Power-Up loading, like causing Power-Ups to reach the 20000ms timeout for Power-Ups to initialize?

Unfortunately, that’s probably how many web browsers work. When a tab is not focused, code execution may be paused to save CPU resources. That can definitely cause Power-Ups to timeout. However, if you observe timeouts that you don’t believe to be caused by the browser trying to save CPU, please let us know.
