Folding resets after restarting VS Code

[Kycko]

Describe the issue

VS Code resets all the folding when I close it and open again. I've found the problem in your extention, see microsoft/vscode#189610.

To reproduce

Fold some functions in .gs file (Google Apps Script, language mode JavaScript), close and then open again VS Code. You will see all the functions unfolded.

• VSCode: 1.85.2
• Explicit Folding: 0.23.1
• Language: Google Apps Script (basically JavaScript)
• Language Provider: built-in?

Code Example

function SH_get_full_range(sheet) {
    return sheet.getRange(1, 1, sheet.getMaxRows(), sheet.getMaxColumns());
}

Settings

"explicitFolding.rules": {
        "javascript": [
            {
                "begin": "{",
                "end"  : "}"
            },
            {
                "begin": "`",
                "end"  : "`"
            },
            {"foldLastLine": true}
        ],
        "snippets": [
            {
                "begin": "{",
                "end"  : "}"
            },
            {
                "begin": "`",
                "end"  : "`"
            },
            {"foldLastLine": true}
        ]
    }

Expected behavior

Save the folding state after VS Code restarts.

Do you have the following settings?

"editor.foldingStrategy": "auto",
"editor.defaultFoldingRangeProvider": "zokugun.explicit-folding",

[Kycko]

foldingStrategy is set to auto by default.
I've changed defaultFoldingRangeProvider to zokugun.explicit-folding, but the issue isn't solved.

I've noticed the folding resets only in the files I see when opening VS Code. If the file is opened but it's in other tab, the folding is saved. 🤔

[daiyam]

The folding state is managed by VSCode so I would incline to say it's a VSCode bug.

I have also the issue when, sometimes, I have extra foldings. It took me a while to understand it was foldings generated by the default folding provider (before switching to my provider), then saved as "Manual Folding Ranges" by VSCode. Solution: command Remove Manual Folding Ranges

[Kycko]

Ran this command, didn't help me.

As I mentioned in microsoft/vscode#189610 the folding state doesn't reset if I disable your extention. Seems there is some conflict in saved folding state and your extention when it's loaded after app start.

Maybe the logs will help?
