I think this bug/workaround has been fixed and we should be able to just change
this to //chrome across the board, but we should investigate and test that in a
separate CL. We might need to change //chrome to declare :chrome_initial or
:reorder_imports as data_deps as well as public_deps, I'd have to look back at
the GN fix to remember exactly the details.

Yeah, I figured this would be better to handle in another CL, as I don't
understand why it was done initially.
