The tmp directory is polluted with webp files

These files are removed in the __destruct function in the ImageAPIOptimizePipeline.php, but I think that function is not called or temporaryFiles is empty.

The other types like jpg, and png are removed from the tmp directory but not the webp, I tried to remove the webp as well, but then the image upload not work.

So now I will not write a cron function to remove the .webp files from the tmp directory. until the issue is fixed.

Same there , using last imagemagick 7.

Thanks for the issue report.

Is this still happening with the latest releases?
