Is this resolved as of PHP 7.3.23 and 7.4.11, respectively, or is
there still an issue?

That output looks actually good to me (besides that exiftool
supports way more tags than we do[1]).

Or is that actually the expected output? I see that exiftool only prints an empty title as well.

On current 7.3 HEAD the "maximum directory nesting level" warning no longer occurs, but
the output still seems to be corrupted: https://gist.github.com/nikic/4759bc05f118e0d4e59b54182c3da8f1

The "Title" is present, but probably filled with null bytes. There's a lot of
"UndefinedTag" going on as well.

Indeed, that appears to be a bug – exiftool processes the image
just fine.
