The only showLearn method I can find in newTab.js is http://searchfox.org/mozilla-central/rev/7aa21f3b531ddee90a353215bd86e97d6974e25b/browser/base/content/newtab/customize.js#110 (#included by the newTab.js source file), but I don't see how that causes a sync reflow.

Possible that the window.open call causes a style flush in our native layer.

Window activation does (when it sets the focus), so... I would guess a new window gets activated while being opened.

Tiles newtab has been superseded by Activity Stream, so I think this bug is WONTFIX.
