vscode: [folding] Don't expand when clicking on space after collapsed line

• VSCode Version: 1.24.1
• OS Version: Windows 7 LTS

Steps to Reproduce:

1. Do either one of these steps:
   • Copy the following code in a blank document that VS Code supports code folding in.
   • Create a JavaScript document, and save it as “foo.js” anywhere.
2. Copy the following code in (or create whatever code you can be syntactically correct in, and it has to have at least 5 lines of codes):

function foo() {
	var create1 = document.querySelector("div");
	var create2 = document.querySelector("div");
	var create3 = document.querySelector("div");
	var create4 = document.querySelector("div");
	var create5 = document.querySelector("div");
	var create6 = document.querySelector("div");
	var create7 = document.querySelector("div");
	var create8 = document.querySelector("div");
	var create9 = document.querySelector("div");
	var create10 = document.querySelector("div");
	var create11 = document.querySelector("div");
	var create12 = document.querySelector("div");
	var create13 = document.querySelector("div");
	var create14 = document.querySelector("div");
	var create15 = document.querySelector("div");
	var create16 = document.querySelector("div");
	var create17 = document.querySelector("div");
	var create18 = document.querySelector("div");
	//... 
}

1. Fold the code function, foo, so it is folded like so:
2. Click outside of Visual Studio Code, so Visual Studio Code is inactive (out-of-focus).
3. Click on the right side of the left bracket on the line, foo() {, in Visual Studio Code. (Basically, clicking on the empty space, so the line indicator is highlighting the beginning of the code-folded line and the text cursor is at the end of the line).
4. Observe that foo gets expanded upon first click, when the correct behavior should be the operating system switching context to Visual Studio Code, and consume the mouse click event without doing anything else.

Here’s a GIF in action:

If we have a list of code-folded functions, and all the user wanted to do was to go back to Visual Studio Code and scroll the document up/down, the user may inadvertently unfold the code, and it would annoy the user to re-fold the code back before continuing to scroll.

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