D403 does not trigger for a single-word docstring that ends with a period #10775

D403 -> Potentially related to #2989

Issue
For a docstring with one word (admittedly not a typical docstring 😉), if the word is not capitalised and there is no fullstop, the correct errors are raised
However, when adding a full stop, D403 is suppressed/not raised
