Fix unwanted behavior with parent filters

[KROT47]

Saw some unwanted behavior when we have some parent with specific filters like:

[{
  category: "my-app",
  sinks: ["a"],
}, {
  category: ["my-app", "with_level_with_filters"],
  level: "info",
  filters: ["someSpecificFilter"],
}, {
  category: ["my-app", "with_level_with_filters", "no_level_no_filters"],
}]

before this PR if we log to ["my-app", "with_level_with_filters", "no_level_no_filters"] then someSpecificFilter will be applied but it seems unobvious since if I just add any level to last config then someSpecificFilter won't be applied, e.g.

{
  category: ["my-app", "with_level_with_filters", "no_level_no_filters"],
  level: "info",
}

Sorry for my late response. I think this is a bug, so could you change the target branch from main to 0.6-maintenance?

Some unwanted commits seem included. Could you rebase it?
