I wrote a test for this years ago; I've thrown it up at <http://stuff.gsnedders.com/html-depth.html>. Chrome limits the DOM at 513 deep (where the root element is one deep), Safari likewise but doesn't paint anything. Edge appears to have no limit, so that TC simply hangs in an infinite loop (presumably it will eventually go OOM and crash, though I wonder if its performance isn't linear?). /g _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
