24bit FLACs muxed in mkv marked as 32bit resulting in no audio on Windows 10

Summary of the bug:
If you try to encode/remux video file to mkv container using flac code for audio you may receive 24bit flac track marked as 32bit track. This causes players to make wrong decisions, for example Windows 10 Movies&TV and Windows Media Player. As a workaround you may need to correct information in mkv header and that fixes the problem.
How to reproduce:

% ffmpeg -i input.mkv -c:v copy -c:a flac output.mkv
ffmpeg version N-78949-g6f5048f Copyright (c) 2000-2016 the FFmpeg developers
  built with gcc 5.3.0 (GCC)

Patches should be submitted to the ffmpeg-devel mailing list and not this bug tracker.
