Bug: Word "I" not Capitalized when First Letter Capitalization Used

Describe the Bug

“Headings should be formatted with capitalization” lowercases words that should always be capitalized when “First letter” is selected.

In practice, this may only mean the word “I”.

How to Reproduce

Steps to reproduce the behavior:

1. Write a heading such as ### What did I learn?
2. Lint
3. The heading is changed to ### What did i learn?

Expected Behavior

No change, i.e.

### What did I learn?

Device

• Desktop
• Mobile

Additional Context

I realize I can add “I” to the list of ignored words, but I shouldn’t have to.

Would it be a correct understanding to say that the ignored words would only affect “Title Case” and the capitalization of the first letter? That is to say it would not affect forcing all caps on the header. Or should ignore words affect all of the capitalization types for the heading rule?

So…I’m talking about “First letter,” not “Title Case.” “First letter” should not lowercase words that are always capitalized, such as “I.” It should also not lowercase any of the words in the “Ignore Words” list. The fix to my mind is to either make “Ignore Words” apply to “First letter” as well as “Title Case” (if that doesn’t cause other conflicts), or to create an “Uppercase Words” list that never get lowercased.

The best way to incorporate this would be to just use the same/similar logic under the hood for both of them. So using ignore words makes the most sense.

This should be fixed on master now and it will go out with the next release. Please let us know if there is an issue with the change.
