Search within topic is omitting results

[Mittineague]

Maybe related to this topic discussing “over-riding browser search” fix?

@codinghorror

topics with > 20 replies do not have all content loaded in the DOM – we only load the visible posts, and unload the rest

-      showSearch = $('.cooked').length < this.container.lookup('controller:topic').get('model.postStream.stream.length');
+      showSearch = $('.topic-post .cooked, .small-action:not(.time-gap)').length < this.container.lookup('controller:topic').get('model.postStream.stream.length');
