Seen result:
I can place breakpoints inside of my unit test and execution will pause correctly, but if I put a breakpoint in the framework, say packages/flutter/lib/src/widgets/scroll_physics.dart the breakpoint will not trigger.

Expected result:
I expect breakpoints in the framework to behave like breakpoints in the unit tests.
