[Bug] `onlyImportantContent` / Tag exclusions appear to have no effect

[jalexy12]

Describe the Bug
Hello! Maybe I'm doing something silly here, but it doesn't seem excluding tags and/or the "only important content" fields seem to have any effect on the outcome.

I've tried this via the playground, via the Go SDK, and via curl, and none of these seem to produce a result I'd expect with the given page.

To Reproduce
Steps to reproduce the issue:

1. Navigate to the playground here
2. Hit "Run"
3. Try various combinations of tags and/or onlyImportantContent enabled/disabled
4. Observe that the response always includes the following:

This navigation bar should very clearly be excluded - it's a header with a nav element inside - both of which are excluded in onlyMainContent and in the manual exclusion list. I've tried with one enabled, the other off, etc - no combination of these seems to exclude this header.

Expected Behavior
No navigation element included in the output

Environment (please complete the following information):

• OS: macOS
• Firecrawl Version: 1 (I think?)

Please let me know if I'm missing something obvious and silly here re: the behavior. Thanks!
