Get the last leaf of a DOM tree (while considering text nodes)

I use this to simulate the (non-existing) :last-letter CSS pseudoclass, e. g. to insert a tombstone Archive at the end of an article:

Copy
findLastLeaf = ($container) -> $children = $container.children() if $children.length == 0 $container else $lastChild = $children.last() $lastContent = $container.contents().filter(-> # Only return nodes that are either elements or non-empty text nodes @nodeType == 1 || (@nodeType == 3 && _.strip(@nodeValue) != '') ).last() if $lastContent.get(0) == $lastChild.get(0) findLastLeaf($lastChild) else $container

Please note that you can't simply say $container.descendants.last() or something similar, since jQuery is ignorant of text nodes.

Flaky tests are tests that sometimes fail for no obvious reason. They are the plague of many end-to-end (E2E) test suites that automate the browser through tools like Capybara and Selenium.
