What is the purpose of t\<300 in the ELB 2xx prebuilt dashboard json?

```auto
\"filter\": {\"query\": \"fileset.name : \\\"elb\\\" and http.response.status_code >= 200 and http.response.status_code\\t< 300\", \"language\": \"kuery\"}

```

This isn't a valid kuery. I'd like to know more. Any help would be greatly appreciated.

Hi @EvanGertis,

Umm, this look like a spurious tab, is this visualization failing? On what version of kibana?
