@selentium You can link issues by using # followed by the issue number – doing so makes things easier for everyone, but particularly maintainers in the case of PRs. Also, if you remove the spaces from the square brackets which you ticked off (by putting an x between them) in the PR template, they'll show up as ticked boxes.

The file which originally caused the Code format check to fail has just been fixed. It'd make sense to rebase master so all the automated checks can run over this PR again.
