Adding +=, -=, and others to nonstandardSymbol doesn't fix formatting for that file

[unbelievableflavour]

Describe the bug
When adding +=, -= and other symbols to Lua.runtime.nonstandardSymbol, errors are removed from the "Problems" tab, and compiling is possible again. But formatting the document doesn't work when foo += 1 is somewhere in the document.

To Reproduce
Steps to reproduce the behavior:

1. Go to a file
2. add

local foo =               0
foo += 1

3. Reformat the document
4. Code stays like

local foo =               0
foo += 1

Expected behavior
Code should look like

local foo = 0
foo += 1

Environment:

• OS: macOS
• Client: VSCode

Reformat nonstandard-symbols, you can't simply say what they are, and I also need to know their grammar features.
it's easy If only '/=' '-=' these are similar to the equal sign.

[unbelievableflavour]

Could you rephrase that? I don't really know what you mean. This is my config file if that helps.

{
    "editor.formatOnSave": true,
    "Lua.runtime.version": "Lua 5.4",
    "Lua.diagnostics.disable": [
        "undefined-global",
        "lowercase-global"
    ],
    "Lua.diagnostics.globals": [
        "playdate",
        "import"
    ],
    "Lua.runtime.nonstandardSymbol": [
        "+=",
        "-=",
    ],
    "Lua.workspace.library": [
        "$PLAYDATE_SDK_PATH/CoreLibs"
    ],
    "Lua.workspace.preloadFileSize": 1000
}

This function is not implemented now, but if I want to implement it, a separate configuration may be required
for example, I need to know that ‘+=’ is similar to the ‘=’

[unbelievableflavour]

If you mean you want to know what += means:

varName += 1 means varName = varName + 1
varName -= 1 means varName = varName - 1

Sorry if that's not what you meant.

[CppCXY]

Well, although you don't understand what I mean, I'm already working on it, just be patient

This issue is marked as closed, though the issue persists for me. It still won't lint. Does the configuration need to be changed or anything?

[sumneko]

What do you mean of 'lint' instead of 'formatting'?

[unbelievableflavour]

I meant formatting, sorry.
When I format my code I expect it to by aligned with other code. As soon as you use += in a line; that doesn't work anymore.

I did some tests and it seems works well
