Before this commit, the line-height of the body was not properly inherited where it should. It is defined as a CSS variable and its value was incorrectly retrieved (if the value is 1.5 and the font-size is 10px, `getComputedStyle` returns 15px instead of 1.5). Other properties related to fonts were likewise improperly inherited. X-original-commit: 12ae698bd9aff8466d69819e0b849752f967c126 Part-of: odoo/odoo#124465
