Great work!
BTW, I will remove user-content- prefix in the next version so that TOC links in exported HTML works as well.
Not sure how to set back MDEPreview.remarkReactOptions.remarkReactComponents.a
Just restore the original A value:
this.MDEPreview.remarkReactOptions.remarkReactComponents.a = this.OrigA
I’m planning to remove jquery from the app dependency in the future. So I would encourage using vanilla JS API.
