Sorry, I don't really have the time to review a PR with this size (=^-ω-^=) I have some important deadlines before mid-december and a lot of work. Sorry for the wait :heart:

Hey @J-ZhengLi, this is a ping from triage, since there hasn't been any activity in some time. Could you rebase on master?

Oh nooo, because I already forgot what I did thus it's kinda hard to distinguish which lines are mine and which are add by others after this PR, at this point it might even be easier if I redo the whole thing (but with less changes I promise). It should be a simple fix tho, I don't know what have I done to make it this complicated 🤦‍♂️

I'm gonna close this and open a new PR tomorrow (hopefully) fixing this again, and sorry @Alexendoo for wasting effort XD
