News pages line up: a news site from 19.9% to 10.9% different
A website rendering release with 5 changes, each checked against the reference browser: text after a block keeps its parent's line height, web fonts kern, and two script fixes for real sites.
Text after a block keeps its parent's line height
Text that follows a block inside the same parent, such as a label above a headline, took the font's natural line height instead of its parent's. On a news site every card headline ran slightly taller lines, and everything below drifted lower. With that fixed, the site's front page went from 19.9% to 10.9% of pixels different from the reference browser, the largest single improvement this arc.
Web fonts kern
Most web fonts keep their kerning in a table Floati read only for system fonts. Web fonts now kern too, so text in them is exactly as wide as in the reference browser and headlines wrap where they should. Two script fixes found on random sites close the release: XMLHttpRequest reports its response headers, and event-handler checks on the window answer as they should.
