Wma file with lyrics

I haven't been able to get the scanner to pick up lyrics from wma (Windows
Media Audio) files. Lyrics in mp3 and m4a files, OTOH, are picked up just fine.
And all other (relevant) tags in wma files are imported flawlessly.

SqueezeCenter v.7.3.3 didn't have this problem.

STEPS TO REPRODUCE THE PROBLEM:
1) Put some text into the "lyrics" tag of a .wma file (e.g.
"lyrics_tag_test.wma").
2) Let the Squeezebox Server scanner scan the folder containing the .wma file.
3) Locate the song in the Squeezebox Server web gui and click on it to view the
song info. Check if the lyrics are displayed. (In my case they aren't).

ATTACHMENT:
Instead of uploading a music track I decided to simply attach a track
containing a few seconds of silence; the important part is the text that I've
provided in the lyrics tag.

Relevant tags in the sample file:
Album artist: lyrics_tag_test
Artist: lyrics_tag_test
Album: lyrics_tag_test
Title: lyrics_tag_test_wma
Lyrics: 
test row one
test row two

ADDITIONAL INFO:
In order to to pinpoint the issue a bit more, I queried the slimserver database
with this sql string (retrieving all wma songs containing lyrics):

select lyrics from tracks where content_type = "wma" and lyrics is not null and
lyrics <> ""

No records were returned from this query. This strengthen my belief that the
issue is caused by the scanner component.
