Neither WebKit, Blink or Firefox seems to replace the child when setting a new value when the element's children consists of a single text node. In Blink/WebKit, the child text node is updated to the new value instead. Ideally, this should be aligned with document.title, but at least Firefox seems to treat them differently w.r.t to mutation observers. 98142 2 ian 2014-01-08 19:19:43 +0000 The text you quote above is non-normative. The normative text already says what you want. 98197 3 1425 davve 2014-01-09 11:29:13 +0000 Created attachment 1425 Compare setting .text to .textContent for <title> Yes, the normative text states: "On setting, it must act the same way as the textContent IDL attribute." which (through the DOM standard) brings us back to replace-all: "Replace all with node within the context object." Neither FF nor Blink/WebKit does this. See attached demo that compares .text to .textContent. Mainly wanted to point out the difference between the map and reality. :) 98201 4 davve 2014-01-09 14:00:18 +0000 I'll try to get this fixed according to spec in Blink.
