1. Put a breakpoint on A1.
2. Put a breakpoint on A6.
3. Start the debugger. It stops on A1 as expected.
4. Use "step out".
5. It goes to the COPY line when I would expect it to stop at A6 given that there's a breakpoint on A6.

FROM alpine:3.22 AS source
RUN echo "A1"
RUN echo "A2"
RUN echo "A3"
RUN echo "A4"
RUN echo "A5"
RUN echo "A6"
FROM alpine:3.22
RUN echo "Hello world"
COPY --from=source . .
RUN echo "B1"
RUN echo "B2"
RUN echo "B3"
RUN echo "B4"
RUN echo "B5"
RUN echo "B6"

I suspect that next also has this same issue when I think about it. It's probably just not as obvious.
