The section this branch adds was the only source of `Microsoft.Contractions`
errors in the file — 9 of them, and vale over the pre-change bytes still
reports exactly those 9, so the count is attributable rather than inferred
from a repo-wide total that was already red.
One of the nine is not a contraction: vale reads `it is` in "Narrowing it is
tracked in ..." as a subject-verb pair, but it is `it` (the object of
narrowing) plus `is tracked`. Rephrased so the sentence leads with the issue
instead, which drops the false hit and the passive-voice warning together.
