Are both spellings the same and correct in Quran?

Salam aleikum, Regarding elongation marks: Do scholars allow to have different categories of elongation marks in Quran ? In terms of pronounciation, it is pronounced exactly the same. What I mean by it in an example (Pay attention to ٱلۡعَٰلَمِينَ): Surah Al Fatiha, Verse 2: https://m.wordofallah.com/1 and https://quran.com/1 > ٱلۡحَمۡدُ لِلَّهِ رَبِّ ٱلۡعَٰلَمِينَ https://myislam.org/surah-fatiha-translation/ and my Quran home: > الْحَمْدُ لِلَّهِ رَبِّ الْعَالَمِينَ After the ‘Ayn there is a small Alif in the first one and in the second one there is a big Alif. Is this allowed by scholars, because I taught the orthography of the bigger letters was always the same (without the harakat and the smaller elongation marks etc.).
