This failure is just an indication that `data:text/html,<input type="number">` is shorter than `data:text/html,<input type="text">` on this theme/platform. This is true on my local platform, as well, actually (Ubuntu 19.04). This is weird & kinda broken. I filed bug 1575969 on that underlying issue. For this bug here, I would strongly prefer a `fails-if` annotation over the patch's current `fuzzy` approach -- this is not really a fuzzy failure, but rather entirely different renderings -- so the ranges in the current patch (773 pixels differing by up to 202) amount to basically allowing the whole test to differ. ("fails-if" works particularly well if we can get a debian-specific condition here, as discussed in bug 1577053.)
