Describe the bug
It is not possible to hit breakpoints in HTML script blocks on code that executes on page load (e.g. code not in a function that will be triggered later by user action)

To Reproduce

repro html:

<html>
    <body>
        <script>
            console.log('log outside a function');
            function clickme() {
                console.log('log inside a function');
            };
        </script>
        <button onclick="clickme()">Click Me</button>
    </body>
</html>

repro launch.json

{
    "configurations": [
        {
            "name": "Launch Chrome",
            "request": "launch",
            "type": "pwa-chrome",
            "url": "http://localhost:5000",
            "webRoot": "${workspaceFolder}",
            "trace": {
                "logFile": "C:/dev/repros/basic/log.txt"
            }
        }
    ]
}

Steps:

  1. Launch the debug session with no breakpoints set
  2. Set a breakpoint on line 4 of the repro HTML above console.log('log outside a function') (the breakpoint should bind)
  3. refresh the page
  4. See that the breakpoint becomes unbound, and is not hit
