Python: UNREPORTED in v8js

[rockdaboot]

With Python payloads, the profiler repeatedly reports frames without symbols ("UNREPORTED").
Additionally, maybe a side effect, the source file name sometimes is incorrectly set to "v8js" for these frames.

These kind of frames are mostly expected at startup, when the symbols are not cached yet.
Instead, they are reported even when the symbols should have been cached - at the same time, a part of these frames have correct symbols (see the screenshot).

Same issue with Python 3.12 and 3.11.
