FileBuffer(p"test.txt", IOBuffer(data=UInt8[...], readable=true, writable=true, seekable=true, append=false, size=0, maxsize=Inf, ptr=1, mark=-1), true, false, false)

julia> read(io, 3)

The current work around for this is:

io = IOBuffer(read(Path("test.txt")))

This is effectively what is happening internally with FileBuffer
