Using mobile interface, the birth/death dates in brackets in the lead sentence of a biographical article are hidden. Latest example seen: https://en.wikipedia.org/wiki/Andrew_Carter_%28composer%29 . Other information in brackets, eg "(1984)" at end of first para of Biog section, is not affected.

Is this a bug or a feature? I see no reason for it - the dates are a key element in helping the reader check quickly whether they've found the right person or are out by a century or two.

I am using a Samsung Galaxy Ace 4 and Wikipedia app beta-2015-08-31.
