Done
In general typings need some love in json-schema-viewer.
It became quite a bit of a hassle once we started addressing all the weirdness and quirkiness.
chore/typings branched my work off here, gonna polish it one day, mostly to utilize tagged union literals and being more careful about malformed data.
I believe we need to take a similar approach as in case of http-spec and assume invalid data is passed rather than the data meets our expectations.

Or we add a transformer to http-spec package to "clean/normalize" json schema to make it valid, so that our entire ecosystem doesn't have to worry about these issues.

That would be some solution as well, but wondering how it'd impact the perf of large schemas processing. If the hit isn't significant, I'd be all in for bringing it to JSV, as right now we kind of need to do the same stuff twice.
