[2020] I have finally found why the Weaver attunements bug! (And another bug reason)

Hello!I've had this issue ever since the Weaver got released - sometimes attunements get stuck and 4 skills are from 1 attunement, and the 3rd skill is the Dual skill. I've wondered what was causing this. And I can see the issue is set as Investigating in the Known Issue Tracker

What I found out is that attunement swap is implemented in an interesting way and has some delay because it loads the different skills asynchronously instead of switching instantly. So when I switch attunements and mount immediately, or do something else to change my skill bar, the attunement gets stuck and the primary one can't be selected to be one full attunement.

Here's a video reproducing the bug: https://youtu.be/KrDDIPgkyHI

And there's also another issue - when I have Fresh Air selected as a trait, sometimes when I switch to Air, all my skills go Air and don't mix with my previous attunement. I think Fresh Air gets activated twice and switches to full Air attunement.

I hope this helps the devs fix the year-long issues :)

Also, I'd like to thank you ANet for doing everything you do for GW2 and its community. You are the best! (The latest episode is a killer <3)
