Yeah, that's actually mentioned in the Outlier release announcement - basically, some of the usage notes are an order of magnitude bigger than what that system was designed for (due to having a bunch of embedded SVGs in them) and that exposed a couple of previously unknown bugs which we'll address in our next update.
Displaying them in the dictionary works fine, though (and isn't silently screwing things up or whatever), it's only the browser that's bugged.
