I've recently been updating and modifying my vim syntax files, and have added a concealment configuration for markdown files. The config itself is working correctly, hiding and displaying the correct info. However it does not apply on file open, even though it correctly applies the markdown filetype. It correctly applies after I reload the filetype. My custom folding applies correctly on initial opening of the buffer, is there something I may be overlooking or is this standard behavior?

My conceal settings follow

~~~ autocmd Filetype markdown,liquid,text \ syn region markdownLink matchgroup=markdownLinkDelimiter \ start="(" end=")" keepend contained conceal contains=markdownUrl autocmd Filetype markdown,liquid,text
\ syn match markdownExt /{[.:#][^}]*}/ conceal contains=ALL

Set conceallevel=3 ~~~
