Failing to remove a breakpoint still removes the breakpoint marker

Does this issue occur when all extensions are disabled?: No

• OS Version: Windows

The problem occurs when trying to remove a breakpoint but failing to do so still removes the breakpoint marker from the UI.

Our debugger extension for embedded can fail to remove a breakpoint from the embedded system due to numerous reason. However, regardless how we structure the SetBreakpointResponse, the breakpoint is removed from the UI but is still active in the debugger. The user has no way of removing the breakpoint but it will still hit.

Reading the DAP doc for setBreakPointsRequest suggests that there needs to be a 1:1 mapping between the list of suggested breakpoints and the actual ones. However, during the remove-step, the list of suggested breakpoint has already excluded the one to be removed to even though we list the removed breakpoint as still active, VS Code does not accept that we failed to remove breakpoint and removes the bp marker.

Steps to Reproduce:

1. Create a breakpoint
2. Remove the breakpoint but fail in doing so
3. The breakpoint is removed from the UI but still left in the debugger.
