Since this has been troubling for a while now...

Seems to work, but would be even better if we could get this fixed in IJ

Do you mean the warning:

Clarifying -
This as a question - by "this" do you mean the issue framed as a question? Like "how to configure intellij not to add a newline after..."

Fixed the violations in the rest of the codebase. Tests will be green now. Can do a final review and merge.
