please help with cloud bikeshed issue?

I'm sorry but I cannot determine what exact problem cloud bikeshed is having with processing the attached index.bs file.

Here's what is happening..


> curl https://api.csswg.org/bikeshed/ -F file=@index-2b72ddf.bs -F force=1 -F output=err > errors.txt ; ls -l errors.txt ; cat errors.txt

I am pretty sure that cloud bikeshed processed this input file (ie at commit 2b72ddf) just fine early last week, and I note that you made a commit to https://github.com/tabatkins/bikeshed "5 days ago" and wonder whether said changes are causing this?

thanks,
