[TYPO3-english] BUG? JS Compressor ignores async flag?

[André Spindler]

Hello list,

I have some js files included in my website.
The first ones are included with async = 0 (resp async is not set), the 
second set of files has async=1 set for each file.
As soon as I enable compression and concatenation, I get two merged 
files, not one(!)
But both of them have the async attribute not set, even the one build 
from all the async files.

Is this a known bug?
