When "type": "wordpress-plugin" was missing on a previous composer update run, the plugin files end up in vendor/.
After "type": "wordpress-plugin" was added, and composer update ran again, the
plugin files will be still in vendor/ and missing in web/app/plugins/svg-support.
Only a manual fix/workaround, by removing the directory in vendor/ and re-running composer update
lets composer update; composer install put the plugin files into web/app/plugins/svg-support/ directory.
