deferred_run doesn't find attached handlers

[dfalbel]

I wonder if this is the expected behavior of deferred_run:

env <- rlang::new_environment()

local_print <- function(path) {
  withr::defer(print("defered"), envir = env)
  attributes(env)
}

local({
  local_print()
})
#> NULL

withr::deferred_run(env)
#> No deferred expressions to run

I know that deferred_run is mostly inteded to run actions in the global environment:

The global environment scenario is the main motivation for these functions.

FWIW deferred_run() executes the deferred expression in withr 2.5

yep expected, it will only work if env is a frame environment currently on the call stack
