Valid spec is mentionned as invalid

[LasneF]

taking the following specification

vacuum raises 3 errors whereas the file looks ok it look like it is interpreting the field $ref as an instruction

Do you know which version the regression occurred in?

[LasneF]

sorry @daveshanley , my mistake , it s not a regression done test since 0.9.1 and issue was there too , just a new use case

[daveshanley]

Got it, will investigate

[daveshanley]

You found an edge case, thank you. This was an issue in libopenapi which has been fixed in `(https://github.com/pb33f/libopenapi/blob/main/index/extract_refs.go#L219) and a test added (https://github.com/pb33f/libopenapi/blob/main/index/spec_index_test.go#L1720)

Fix is available in vacuum v0.9.15
