Describe the bug

Hi!

Trying vite with HRM I found that by adding a breakpoint (in the browser inspector) on a js file and then changing something in that file, the breakpoint is lost. This doesn't happen with JSX files. To try this I added a stackblitz where there is a counter.js file. Add a breakpoint on the js file and then modify something on it, the breakpoint will vanish.

Thanks.

Steps to reproduce

Add a breakpoint to the counter.js file and then modify it.
