Tracegraph "open" displays wrong data

[protopyte]

Scenario: tracegraph traceA -> overview -> open traceB -> overview

This is what is expected:
tracegraph traceB -> overview

I can reliably reproduce the issue. Both DBs are ~550MB.
If that matters:

• traceA: 440k BB, 5M instr, 2.9M mem accesses
• traceB: 400k BB, 4.3M instr, 2.5M mem accesses

Beside the graphical issue, the information at the top right should also be reset on open, I think they belong to traceA while traceB is displayed.

Thank you
