Reduce transition height in timeline on large tracks

[hellopaul4]

When working with transitions in the timeline, if I resize the track to be big (so, for example, I can see the details of an audio waveform) any transitions also grow to a ridiculous size, partially obscuring what's behind them. It'd be nice if, when embiggening a track, the transitions grew only to a certain size, then remained at that size, exposing more of the track details behind it. Nobody needs a transition to be this big:

Something like this would be a lot more civilised:
