English spelling stops working when it's used together with a Ukrainian dictionary

[ghost]

Description of the bug

When I add the Ukrainian dictionary to the dictionary list, English one stops working.

Steps to reproduce

1. Download the Ukrainian dictionary
2. Extract and put it into the Packages/User/Dictionaries
3. Update Sublime Text dictionary setting

{
	"dictionary": [
		"Packages/Language - English/en_US.dic",
		"Packages/User/Dictionaries/uk_UA.dic",
	],
}

4. Create a new text file with the next content

Thiiis is the речення with ісьюз.

5. Enable spell checking

Expected behavior

Thiiis & ісьюз should be marked as words that have spelling issues.

Thiiis is the речення with ісьюз.

Actual behavior

Only ісьюз is marked, but Thiiis it seems ignored.

Running hunspell directly it looks like that dictionary simply marks all ascii-words as correct. So ST is doing the right thing here:

$ hunspell -d uk_UA
Hunspell 1.7.0
Thiis
*
$ hunspell -d en_US
Hunspell 1.7.0
Thiis
& Thiis 3 0: Thais, This, Thins

Thanks for the answer, it helped to find the reason. This one describes how to change the *.aff file to fix the issue.
