ffprobe does not output bitrate for webm files

[xamarin]

Summary of the bug:
How to reproduce:
Try to get directly audio and video bitrate for a given .webm file. Doesn't work:

% ffprobe -v quiet -select_streams v:0 -show_entries stream=bit_rate -hide_banner -of default=noprint_wrappers=1:nokey=1 -i video.webm
N/A
% ffprobe -v quiet -select_streams a:0 -show_entries stream=bit_rate -hide_banner -of default=noprint_wrappers=1:nokey=1 -i video.webm
N/A

However, raw output does show the values:

% ffprobe video.webm
