"One Letter" never recognized as incorrect spelling

[vark8]

1. Ignore Words -> One Letter -> Unchecked
2. Typing any single letter is not recognized as incorrect

Example: Meant to type "This is a game" but accidentally typed "This is s game" there is no indication of an error.

Can confirm the issue but it might be deliberate choice by Hunspell dictionary unfortunately, for Russian language for example it seems to work (and one letter words are ignored correctly if the option is turned on so it's not an issue with utf-8 or something).

Might be due to the fact that people complained about marking abbreviations with dots as misspellings. Native speller for English seem just to correct lowercase i into uppercase. But I will double check anyway
