Issue: Crash while debugging with chrome after rebuild of code
Labels: bug,needs info

Version: Deno 1.46.1

**Crash while debugging with chrome after rebuild of code** (see stack trace below)

**Repro steps**
1. Start deno app with command: `deno serve --inspect --watch --allow-env --allow-read --allow-net --allow-ffi --unstable-ffi --port 9092 src/main.ts`.
2. Use chrome `128.0.6613.119 (Official Build) (64-bit)` as debugger.  Click the Inspect link in the chrome://inspect/#devices page for the deno remote client to open a DevTools window.
3. Add a break point and step through the code.  All works.
4. Make a change to the code so that the deno process restarts.
5. Close the chrome DevTools window and open a new one by clicking the Inspect link again.
6. Step through the code again.

**Expected result**
Debug app.

**Actual result**
deno crashes with the following stack trace:
```

```
The code that causes the crash is related to String and regex:
```
const matches = content.matchAll(/\${{.*?}}/g)  // `content` is a String
for (const m of [...matches].reverse()) {       // <--- crashes when stepping over this line
```
The command line args `--allow-ffi --unstable-ffi` are used here because the dependency `jsr:@db/sqlite@0.12.0` requires it.
