Discovered in April 2005, bug 290125 will soon be fixed. The Mozilla Firefox browser will correct this small display error in February, which causes the line height of certain texts to be incorrect.
It has been a long time since Internet users have alerted about a style problem on the Mozilla browser. The bug was listed on April 12, 2005. But it was not until February 2023 that it would disappear forever, with the deployment of version 110 of the software.
Misreading a CSS pseudo-element
After 18 years, case 290125 was finally repaired and closed on December 20, 2022. The error concerned the formatting of the first letter of a paragraph, details NextInpact. More specifically, it is a misreading of the CSS::first-letter pseudo-elementwhich changes the appearance of the first letter of a block of text.
The browser’s rendering engine, Gecko, did not previously take into account the line height modification associated with this letter. According to Jonathan Kew, developer at Mozilla, the solution lies in a patch that will allow you to choose between a classic, new or automatic behavior of Firefox.
