The test case #310 is similar to #216 by Max Reitz. The difference is
that the test #310 involves a bottom node to the COR filter driver.

An ascii-art of what we have done won't hart, like:

Better assert what it should be instead of what it should not:
assert qemu_io_silent(top_img_path, '-c', 'read -P 0 0 1M') == 0
> + assert qemu_io_silent(top_img_path, '-c', 'read -P 2 1M 1M') == 0

> + assert qemu_io_silent(top_img_path, '-c', 'read -P 1 3M 1M') != 0
and here
assert qemu_io_silent(top_img_path, '-c', 'read -P 0 3M 1M') == 0

you shouldn't modify 307... line here, and I think "export" is unrelated.
so, with 307 as is, and add 310 without "export" group, and also two my previous suggestions:
