I would like to upgrade grunt related dependencies and this was in the way: updating only the grunt dep without the thirdparty didn't seem good.
I renamed less-2.5.1.min.js to simply less.min.js, you can see the version in the comments inside the file.
could we maybe switch to npm dependency instead?
I'm all for moving to npm.
But has pointed out before by @busykai, we need to do something about the increase size of the bundle.
For example less 2.7.1 from npm is about 3MB, but the minified file is only 140kB.
I have some random thought but still nothing good.
Is it about npm not providing minified file or about npm providing too many files that we don't need?
Too many files, I've opened #13020 as a possible solution
Upgrade less from 2.5.1 to 2.7.2
Now it is fetched from npm.
