Description

I'm using MacVim 8.2.261. I have installed folding.vim so that it is found by vim. (vim 8 packages) I have verified that it is found by running :scriptnames. I have verified that foldmethod=expr.

If I choose to edit a markdown file first thing on opening vim, it folds properly - it opens in a completely folded state and I can open and close the folds as expected using the vim keys.

However, if I open .vimrc first (for instance) and then open a markdown file, it opens completely unfolded and fold command are ignored.

I have discovered, though, that if I source folding.vim after that, then folding works again.

I'm reasonably certain I have set everything up as stated in the GitHub site. Do you have any idea what might be going on?

Research direction

Reproduce the behavior by opening .vimrc before a Markdown file, then compare it with opening the Markdown file first. Inspect folding.vim and the Vim settings shown in the report, especially foldmethod, and confirm that Markdown folding is initialized automatically after the filetype change without manually sourcing folding.vim.
