No formatting or concealing of italics and so on in blockquotes

I am not sure that this is a vim-markdown issue, and I don't know how to check whether it is, but my italics appear in italics with the underscores concealed, expect inside block quotes.

Same happens to me when trying to make a word bold inside a sentence in italics words. Something like:
_This is a **sentence**_
It's shown as:
This is a **sentence**
Here in github it works fine:
