Description

Whenever I'm in debug mode, I make changes to the code, save it and try to add a breakpoint to the newly added line, the breakpoint is unbound. The sourcemap cannot detect the newly added line.

Minimal Reproduction

Run the application in debug mode.
Make code changes.
Save and wait for it to detect changes and reload.
Set breakpoint in newly added line.
Breakpoint is unbound or breakpoint is set at random location.
