Zip html in docs.rs looks misgenerated

[sftse]

Html in online documentation for all versions of zip looks off. Where the VERSIONS box normally appears the title bar seems to have been rendered.

Searched for duplicates, found nothing.

Chrome dev tools detects the issue:
"Duplicate form field id in the same form"

[syphar]

looking into it.

it seems like the version-partial URL returns a 404. not sure why

[syphar]

I think this is a regression from #2933

[syphar]

( or a caching issue, just trying to reproduce locally)

[syphar]

the interesting question is why this only broke for zip.

[syphar]

so, the wrong partial url is generated only when the latest release failed, which it did for zip.

[syphar]

the fix itself (based on the deployed version) would be syphar@1d39135, plus some tests.

Though perhaps I'll deploy the current master branch, which includes a bigger refactor that also solves the issue.
