IIUC, the approach you choose here is to let `SemaPPCallbacks` control the "entered file stack" and allow it to remove element (which is file) from middle of the internal stack in `TimeTraceProfiler`, but this creates async event which is not designed for this purpose.

Can we let `SemaPPCallbacks` track the last push file into the stack and when exit file, pop all the elements from the stack until we popped the last pushed file?
