wp_generate_attachment_metadata generates scaled images

[picard102]

When using wp_generate_attachment_metadata() it seems to ignore the filter to turn off "big_image_size_threshold".

add_filter( 'big_image_size_threshold', 'return_false' );

$generateThumbs = wp_generate_attachment_metadata( $attachmentId, $file );

This results in a scaled version of the media being created and _wp_attached_file meta being replaced with the scaled versions path.
