Unseekable S3 StreamWrapper says it is seekable

[driskell]

Describe the bug

When using a S3 stream wrapper and opening a file, without setting seekable, so it is unseekable, the stream meta data says it is seekable.

Expected Behavior

Stream metadata should say not seekable

Current Behavior

Stream metadata says it is seekable when it is not

Reproduction Steps

$file = fopen('s3://...', 'r');
echo json_encode(stream_get_meta_data($file));

{"timed_out":false,"blocked":true,"eof":false,"wrapper_data":{"context":null},"wrapper_type":"user-space","stream_type":"user-space","mode":"r","unread_bytes":0,"seekable":true,"uri":"s3://..."}

Hi @driskell,

Thanks for reaching out. This is an unfortunate quirk of the streamwrapper customization and it doesn't look like there's a great way for us to override this.

We've documented our reasoning behind making streams opened in r unseekable by default and outline the steps needed to make a stream opened in r mode seekable.
