Testing further with ruby-rails-assets-underscore, the test is passing 
even with a broken symbolic link.

Try building master branch which has this commit
https://salsa.debian.org/ruby-team/ruby-rails-assets-underscore/-/commit/194c526208b3be29870f745d9ac0bfbc9af6d66c

Without libjs-underscore in build depends, the test should fail, but it 
is passing.
