Many "Children are longer than parent" warnings when loading crox output in chromium profiler

For example:

```
[70573:70573:1111/154348.180968:ERROR:CONSOLE(1)] "Children are longer than parent at 1699713671459.944 (18214.109 by 0.002", source: devtools://devtools/bundled/models/timeline_model/timeline_model.js (1)
