[Bug]: Rspack Dev Tools Slow

What subject does this issue tracking?

Hi some of my team members have reported the below issue when serving an app and debugging , so wanted to check if others are experiencing the same issue:

1. I noticed that the devtools within Edge's sources tab seem really slow to load with Rspack building. I think it was working fine without rspack, so I think the critical difference is using it.
   It seemed like everything was using these giant relative paths last time I tried to use it, so everything loads in some sources folder in Edge. Initially I thought it might just be me but a few other members of my team also seem to be running into the slowness.
2. I frequently have my whole tab freeze / crash while I try to do anything (ex: nav through the stack trace) in the sources tab when a breakpoint is hit.
3. my devtool window responses slowly, hitting a break point will just cause the devtool window crashes.
4. Debugging is becoming extremely difficult with rspack. Most of the times, the dev tools just freezes and there is nothing I can do except restarting the browser again. Even after restart, the very next time, it hits a breakpoint and immediately freezes up again.

Any pointers as what might be wrong here?
