Markdown Heading Editor Folding Not Working

[lamyergeier]

• VSCode Version:1.49.1
• OS Version:Ubuntu 20.04.1

Steps to Reproduce:

1. The markdown folding as illustrated in [folding] Add code folding for markdown based on heading level · Issue #3347 · microsoft/vscode, doesn't work. I don't get the option to fold it

Does this issue occur when all extensions are disabled?: Yes

[mjbvz]

Please markdown code that demonstrates the problem

[lamyergeier]

@mjbvz

I opened the following markdown file after disabling all extensions

Observation

We can see that we don't get the V symbol for headings (should be located on the left pane of the headings), so we are unable to minimize it.

That example works fine for me:

Did you disable the built-in markdown language features extension?

[mjbvz]

Or actually, either you've disabled the built-in extension or have changed the "editor.foldingStrategy" setting to be indentation based instead of smart (auto)

Interestingly I'm having a very similar problem using Org Mode after just updating VSCode. It no longer recognizes the asterisks as the headings that should be folded, and will only fold lines that start with a dash like the OP showed here.

I struggled with this too for a while, even after checking the "Editor:Folding" setting, which was mysteriously off by default. But it appears that some folding arrows only appear when you mouse over the gutter (like Markdown), but other arrows are persistent (like list-level folding).
