Layout Renders Partially – How To Fix

Last year I wrote in-depth about ExtJS "heavy" JavaScript layout system in Sencha's blog: http://www.sencha.com/blog/exploring-the-layout-system-in-ext-js-5-and-sencha-touch

Recently I discovered a rather interesting "issue" that all big ExtJS apps will hit eventually: the app will start "misbehaving" in a sense that very complex sections will sometimes render only partially and the UI will become unresponsive. This one will be extremely painful to figure out, as this is actually a result of a "silent failure" by the ExtJS layout system, due to a pre-emptive assumption of "if you're running too much layout, you probably did something wrong" by the framework.
