Summary: The VS Code DAP expects on response for each breakpoint that was requested. If we responsd with multiple entries for one breakpoint the VS Code UI gets out of date. Currently the VS code DAP doesn't handle one breakpoint with multiple locations. If this ever gets fixed we can modify our code.
