"Size increase" warning shows up incorrectly for alpha versions that are older and smaller than the latest release

[connorshea]

Describe the bug

For example, the package size of oxlint has decreased in newer versions, but if you look at the "alpha" version (v1.17.0-alpha.0) from a few months ago, it shows as though the package is increasing in size, because the "before" version it's using for comparison is the newest version, 1.57.0: https://npmx.dev/package/oxlint/v/1.17.0-alpha.0

Additional context

v1.17.0-alpha.0, September 2025: 19.7 MB

v1.57.0, March 2026: 14.9 MB

Ideally, npmx would not display a warning when viewing the old alpha version. This is maybe due to some weirdness in how version comparison works in semver? I'm not really sure.
