exif_read_data() returns fields incorrectly for camera RAW files

[t-rutter]

Description

May possibly be related to #11020

The following code:

<?php
$exifData = @exif_read_data($filePath);
echo $exifData['StripOffsets'] ."\n";
echo $exifData['StripByteCounts'] ."\n";
print_r($exifData['BitsPerSample'])

Resulted in this output:

160528
57600
Array
(
    [0] => 8
    [1] => 8
    [2] => 8
)

StripOffsets does not reference either the start of the main image data or any other data portions like previews.

Below are values return by exiftool and been check to be valid
But I expected this output instead:

1557504
16916475
Array
(
    [0] => 14
    [1] => 14
    [2] => 14
)

exif_read_data() should return valid field values or not return them.
No warnings or errors from PHP
