Unfortunately, this is a known bug that's very hard to solve. Since we
use a regular expression to parse tags, there's no way to handle
balanced characters like '{' and '}'. The only way to really solve this
would be to move to manually parsing the tag. This is something we'd be
interested in, so if you want to work up a patch for it, go for it
(check out render_tag in lib/haml/engine.rb).
