This can make a quite uneven layout if you have some short and long titles.

Personally I saw this as a feature more than a bug (better use of space / less wasted space), but I could see how others might disagree.

I would first look into if some CSS could be used to force all the elements to have the same (maximal) height. Alternatively, you could probably use CSS to just set a min height in pixels for that element type

Thanks, I'll check what CSS can do.

I agree with @larsoner that this is a feature: it helps minimizing overall space on small devices.
However, I guess you can easily set a min-height in your custom CSS 🙂

Customizing with min-height should be good enough.
