Who decided indenting with spaces was a good idea?

It's not a problem working with others, since you can replicate this manually without much effort.

Let's say I have the following code:

        if (test1) {
            if (test2) {
                executeSomething({
                    "first"  : "1st",
                    "second" : "2nd"
                });
            }
        }

Here's the same code with spaces replaced by "S" and tabs replaced by "T":

    TifS(test1)S{
    TTifS(test2)S{
    TTTexecuteSomething({
    TTTT"first"SS:S"1st",
    TTTT"second"S:S"2nd"
    TTT});
    TT}
    T}

You could set your IDE to use tabs, and then for fine-grained indentation (where I've lined up the property definitions in the object), you'd use spaces.

Many IDEs and text editors will automatically detect indentation settings, and some of the popular ones (WebStorm, Netbeans, I think vim) also support hybrid indentation.

So it's only really a problem when someone uses a plain-text, Notepad-like text editor, but I haven't met a professional developer who does that in a long time.

  TTifS(test2S&&
  TTSSSStest3)S{
  // ...

Show me an editor which can tell indentation from alignment at the beginning of the line. And moreover, which can tell it for a dozen of unrelated languages, like Perl, C, make, Erlang, XML and YAML.

All IntelliJ products[1], vim[2], and emacs[3] support this. They call it "smart tabs". Sublime has a plugin that does something similar[4].

I don't have it installed and can't find documentation for it, but I believe NetBeans does this by default.

Again, this is something that usually happens naturally when you're indenting with tabs. Very few humans or programs are going to do alignment with tabs, even if they're indenting with them.

OK, and now explain me why none of these work correctly with all the mentioned languages.

They work fine with Perl, C, XML, and YAML. I wouldn't know about Erlang, but I'd imagine they work with that, too.

It seems as though you have an idea in your head that you're unwilling to research, and when I present you with information, you're unwilling to accept that you could be wrong.

Or do they? Either they are language agnostic or they are not. If they are language-independent, they can't work properly, since indentation and alignment are syntax-specific (that is, need some information extracted from syntax). If they are language-specific, they can't work with all the languages I happen to need, which may include some DSLs rarely used by programmers and some languages defined by myself. I see no other option.

I have checked plugin for Vim; it doesn't work as you advertise. It either puts only spaces or only tabs at the beginning of the line, depending on expandtab setting. I assume from your comment that others work as well as this one.
