Web: Breakpoint disabling impossible

Steps to Reproduce

1. Run Flutter Web in Intellij and create some breakpoints in the debugger
2. Wait for them to get hit (they wont get marked as detected ->so no little checkmark)
3. Disable the breakpoints (click on them so they disappear)
4. Hot reload -> they will still get hit

At this point it is impossible to run without the breakpoints, “disable all” is also not working. The only thing that works is manually restarting the entire application.

This seems not to be exclusive to Flutter web in Intellij. I also have this problem in VS Code.
