Page freezes when using `Proxy`

Page freezes when using Proxy

Description

When writing native JavaScript code in the editor, the page freezes immediately after defining a Proxy object and inputting an empty block {} in the get method. The page becomes unresponsive and no further actions can be performed.

Steps to Reproduce:

1. Open the editor.
2. Enter the following code:

   const obj = { a: 20 };
   
   const proxy = new Proxy(obj, {
     get(target, p){} 
   })

3. Press Enter.
4. The page freezes and becomes unresponsive.

Expected Behavior

The page should properly handle the Proxy definition without freezing or entering an infinite loop.

Current Behavior

The page freezes without any error message, and it seems like an infinite loop occurs. The developer tools cannot be opened during this process.

Environment Information:

• Browser: Edge v132.0.2957.55
• Additional Configuration: The issue occurs while writing native JavaScript using Proxy.

Thanks for reporting!

You actually discovered at least 2 different problems in the jsrepl implementation. I'm working on a fix. Proxies are tricky, but I'll try to support them properly.

For the record:

A similar problem with infinite loop, but the page doesn't freeze. JSRepl handles circular refs, but it doesn't work for the reported issue and in the following case
