JS class privacy tag syntax error injected upon file save

[dshipp25]

Issue Type: Bug

When the file is saved, the class private Hash tag is separated from it's identifier, introducing a syntax error. This code demonstrates:

class testthis {
  #privateProperty;
    constructor() {
        this.#privateProperty = 0;
    }
    #privateMethod() {
        return this.#privateProperty;
    }
};

Upon saving the file, it becomes

class testthis {
    #
    privateProperty;

    constructor() {
        this.#privateProperty = 0;
    }

    #
    privateMethod() {
        return this.#privateProperty;
    }
}; which causes an error during code interpretation - identified missing after #.

Extensions: none (all disabled to retest error...)

Are you using built-in TS version (used for JS as well) or workspace version?

VS Code 1.58.2 ships with VS Code that doesn't produce this result.

Extensions: none (all disabled to retest error...)

You used command line flag or F1 and >Developer: Reload Window With Extensions Disabled? Some extensions require window reload to be completely diusabled?

Do you have any actions configured in case e.g. editor.codeActionsOnSave? Do you have any watchers/formatters outside of VS Code?

Thank you for such a quick response. I'm new to Visual Studio Code so I can't answer many of your questions properly (TS version or workspace, I'm not sure...) I'm am using v1.58.2 so your comment makes me think I didn't properly disable the extensions. I have not installed any watcher/formatters myself other than an extension that uses Beautify.

Before my message, I just clicked disable on each extension and tried to verify they were disabled, but wasn't sure they really did. Just now, I used your F1 command and the problem did not reoccur. I then reenabled extensions, disabled or uninstalled all of them, reloaded VSCode and reinstalled one by one. I found the culprit: JS-CSS-HTML Formatter. I won't be using that one now.

Thank you for your guidance. Problem solved.
