for data frames, recycle = TRUE drops attributes

[moodymudskipper]

We can't recycle args that have attributes that don't support recycling, which I think is all of those unless the class supports them.

A use case that might have all the corners we need : POSIXct with and without extra args

plt <- ggplot2::ggplot(cars[1:2,])
constructive::construct(ggplot2::layer_data(plt))
#> {constructive} couldn't create code that reproduces perfectly the input
#> ℹ Call `construct_issues()` to inspect the last issues
#> data.frame(PANEL = factor(c("1", "1")), group = -1L)
constructive::construct_issues()
#> `attr(original$group, 'n')` is an integer vector (1)
#> `attr(recreated$group, 'n')` is absent
constructive::construct(ggplot2::layer_data(plt), constructive::opts_data.frame(recycle = FALSE))
#> data.frame(
#>   PANEL = factor(c("1", "1")),
#>   group = c(-1L, -1L) |>
#>     structure(n = 1L)
#> )
