The 'random' function on the song select screen exhibits several strange behaviours

[tovc]

1. The 'never repeat' option does not seem to work properly. This does not seem to be entirely non-functional, as 'true random' results in repeated songs much more often, but they still occur with 'never repeat' enabled

2. The 'random' button does nothing when only a single mapset is filtered in the beatmap carousel, instead of randomly selecting a beatmap from the set. osu!stable does not display mapsets on the carousel, so it will select a random beatmap regardless of filtered maps

3. The 'random' button does not even select a random beatmap, but rather a random mapset. Note how the only maps selected are 'Broly's Extra', 'Oh Baby' and 'Nymphe's Extra', and none of the other beatmaps in the mapset. Again, osu!stable's behaviour differs from this, and will select a random beatmap in the set

I've made this an idea instead of an issue primarily because I don't know how much of this is intended behaviour. The button is just referred to as 'random' everywhere I know of. It's never referred to as 'random map' or 'random mapset', so I don't know which is the intent. I've always thought of it as a 'random map' button, as that's how it functions in stable, but this might be an intentional change. I personally prefer stable's functionality, as it results in me actually playing more of a set than I otherwise would
