--stroke seems to stop .png file generation #2736
Description
Generating d2 -t 8 --pad=20 --sketch --layout=elk -> doc/images/scenario-remediate.svg works well but d2 -t 8 --pad=20 --sketch --layout=elk -> doc/images/scenario-remediate.png produces exactly the same file length as svg. Removal of the --sketch then produces a working png.
