Mozilla Memperbaiki Bug CSS 18 Tahun Lalu di Peramban Firefox

December 29, 2022 by Flamango

Mengapa penting? Ada kelemahan perangkat lunak yang cenderung bertahan bahkan di proyek yang paling aktif. Peramban sumber terbuka seperti Firefox, bagaimanapun berusaha untuk menjadi pembuat rekor sejati dengan bug yang sudah berumur puluhan tahun diperbaiki tepat pada waktunya untuk Natal.

Cacat pada peramban Firefox terselesaikan tepat setelah dewasa. Bug 290125 pertama kali dibuka 18 tahun lalu ketika pengembang Mozilla menemukan bahwa browser open source tidak benar dalam menangani elemen pseudo CSS ::first-letter.

Elemen semu CSS ::first-letter menerapkan gaya ke huruf pertama dari baris pertama elemen tingkat blok, tetapi hanya jika tidak didahului oleh konten lain. Gecko, mesin tata letak Firefox, mengabaikan ketinggian garis yang dinyatakan dan mewarisi ketinggian garis dari kotak induk.

Perilaku yang salah mencegah penulis memposisikan huruf pertama dengan mengurangi kotak garis melalui penggunaan tinggi garis kecil. Hasil akhirnya adalah Firefox membuat huruf pertama salah, di mana browser lain saat itu menangani fitur CSS dengan benar.

Perbandingan hasil penulisan huruf pertama Firefox dengan browser lain

Masalah awal dilaporkan pada 12 April 2005 dalam rilis besar pertama Firefox (1.0). Kemudian perbaikan pertama datang dengan Firefox 3.0 pada tahun 2007, ketika rendering ketinggian garis berbeda pada platform Mac diselesaikan oleh pengembang Mozilla. Bug tersebut kemudian dibuka kembali pada tahun 2014 ketika CSS Working Group, dan selesai pada 20 Desember 2022.

Menurut penjelasan pengembang Mozilla, Jonathan Kew, solusi yang sedang diadopsi adalah tambalan yang dirancang untuk meminimalkan risiko dan membuatnya mudah untuk beralih antara perilaku lama yang ada dari mesin tata letak Gecko dan perilaku kompatibel yang baru.
