HEADWORD LIST SORTING (Greek alphabet)

[mylonojr]

Describe the bug
There seems to be a problem with the sorting of Greek words in the headword list when it comes to stressed and unstressed vowels.
The stressed form of a vowel takes precedence over any other letter (be it an unstressed vowel or a consonant).
For example, the word "άγιος" appears before the word "αβρός", even though the letter "β" (beta) is the second letter of the Greek alphabet while the letter "γ" (gamma) is the third.
Also, the word "έψιλον" (the letter "ε" being the fifth letter of the alphabet) appears before any other word beginning with any other preceding unstressed vowel or consonant.
Of course, the same thing happens in the case where the stressed vowel is the second, third, ... letter of a word and the sorting of words with identical first (2-n) letters depends on the stressed vowel.

To Reproduce
Just try the words I mention in the previous paragraphs

Expected behavior
Words in the Headword List should be sorted regardless of a vowel being stressed or unstressed. That is, the letter "ε" (epsilon) is always the fifth letter of the Greek alphabet and should always come before subsequent and after preceding letters, whatever its form (stressed or unstressed)

A temporary solution I came up with:
I added a hidden field where i add the word in capital letters (words in capital letters are not accented in Greek)
In "SETTINGS" -> HEADWORD LIST, in the first drop-down list (HEADWORD), I select the element which contains the entry's headword while in the second (HEADWORD SORTING) I select the hidden element with the capital letters.
It appears to be working, although I have to type in the same word twice.
