Breakpoint hit -> window gets focused -> VS Code freezes for some time

• VS Code Version: 1.56.0
• OS Version: Windows_NT x64 10.0.18363

Steps to Reproduce:

1. Set breakpoint in js.-file
2. Launch debug-session in browser (all breakpoints in dev-mode disabled)
3. Switch to browser window
4. Maximize browser (because it is just half open)
5. Hit breakpoint
6. VSCode blinks in taskbar -> switch back to it
7. VSCode freezes and waits for something

Hints:

• By avoiding step 4, this issue doesn't occur.
• Minimizing and maximizing VSCode while its freezed solves this issue.
• This issue also happens in insider-version of VSCode.

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

Launch configuration (no, this problem is not related to brave, it happens also in google chrome):

{
    "name": "Browser debug",
    "request": "launch",
    "type": "pwa-chrome",
    "runtimeExecutable": "C:/Program Files/BraveSoftware/Brave-Browser/Application/brave.exe",
    "runtimeArgs": ["--remote-debugging-port=9222"],
    "url": "http://127.0.0.1:5000",
    "webRoot": "${workspaceFolder}\\memory-viewer\\server",
    "pathMapping": {
        "/css": "${workspaceFolder}\\memory-viewer\\server\\static\\css",
        "/app": "${workspaceFolder}\\memory-viewer\\server\\static\\app",
        "/js": "${workspaceFolder}\\memory-viewer\\server\\static\\js"
    }       
},

This looks like a regression of the issue mentioned in #116865, #117780, and others and declared a duplicate of #114459. It was fixed in 1.55 but it's back. Super annoying.

First breakpoint successful, then I triggered it again with no success.

@maxhausmann can you reproduce if you start vscode with
code --disable-features=CalculateNativeWinOcclusion <path to workspace/folder>

With
code --disable-features=CalculateNativeWinOcclusion <path to workspace/folder> this issue does not occur.
I tested it with several sizes of the browser-window (see initial text) and the breakpoint got hit instantly.

Additonal information: CMD says "Warning: 'disable-features' is not in the list of known options, but still passed to Electron/Chromium."
