It's part of React Spectrum, which we're trying to avoid updating at this time because we're phasing out usage of the libraries and upgrading them is painful.
Because the author of the vitest PR used the semantic commit naming convention, Renovate now thinks our entire repo uses semantic commits and has renamed all of its PRs.
A couple different people (me and Dave) have tried and failed to find an easy way to upgrade these, and in the future we won't need these dependencies at all once the switch to Compound Web is finished, so let's not generate Renovate PRs for them.
