I’m not 100% sure on how to reproduce this, but I was jumping in and out of topics fairly quickly this morning, using the “back” button on my mouse. That is:
- Hover over oldest topic, and click it.
- When done, without moving my mouse (much), click the physical “back” button on my mouse.
- Move the mouse up to the next topic, and click it.
I would imagine that there would be less than a second, maybe less than half a second, between steps 2 and 3. Clicking “back” will reload the topic list, so I’m not sure if it’s a race condition – the call to change the favicon gets cancelled because I load another topic too quickly – or if it’s unrelated and just a bug from using the “back” button. I wouldn’t expect the latter, as I would imagine many people would have run into it before now…
Clicking the main “home” logo doesn’t correct the issue, but refreshing the page does.
