As requested here I'm creating this ticket to track the application of a branch-specific fix to 7.0.x-private.
Motivation: this PR to the "master-private" branch had spurious source formatting problems reported because of formatting issues in the lcs/lcs-client-web module from the 7.0.x-private branch, which gets overlaid onto master-private when the working directory gets set up.
In practice, we don't expect this kind of thing to be frequent because later "master-private" tooling does a better job of running only against changed files. Nevertheless, the "deep" fix of actually fixing the files on 7.0.x-private is easy (just run "npx liferay-npm-scripts format:check") and automated (ie. minimizing real risk of human error), so we might as well do it.
