data_frame does not recycle when the argument to recycle is the first argument.

I would expect the following to be a data frame with 10 rows, and two columns, however data_frame returns only one row.

data_frame(x = 'hi', x = runif(10))

However this works correctly if the recycled column is not the first

data_frame(x = runif(10), y = 'hi')

looking at dataframe.R#L67-L77 it looks like it should be working regardless of the order. I will try and figure out what is going on.
