Inherited link is not qualified with namespace

[lionel-]

With

#' @inheritParams vctrs::vec_cast

R CMD check produces this warning:

❯ checking Rd cross-references ... WARNING
  Missing link or links in documentation object 'vctrs.Rd':
    'stop_incompatible_type'
  See section 'Cross-references' in the 'Writing R Extensions' manual.

Because the inherited link contains a link that isn't namespace-qualified:

\item{x_arg}{Argument names for \code{x} and \code{y}. These are used
in error messages to inform the user about the locations of
incompatible types (see \code{\link[=stop_incompatible_type]{stop_incompatible_type()}}).}

Minimal reprex:

rd <- roxygen2:::parse_rd("\\link[=stop_incompatible_type]{stop_incompatible_type()}")
roxygen2:::tweak_links(rd, "vctrs")
#> \link[=stop_incompatible_type]{stop_incompatible_type()}
