should hopefully make Matomo compatible with 7.3 and maybe even fix other issues without creating new ones.
Be good to run the Jshrink tests with PHP 5.5 maybe. Looks like they run tests only for PHP 7+. Could obviously also easily regress later. Not sure if UI tests use the minified version or not (I think they do)
BTW @Findus23 can you rebase/merge w/ 3.x-dev? I can't seem to get composer to create the composer.lock file correctly, it always includes two JSShrinks.
