Patch Changes
- Remove the byte order mark (BOM) from the compiled CSS.
dart-sassprepends it when the compiled CSS contains non ASCII characters and thestyleoption iscompressed(the default for theproductionmode), but a BOM is only valid at the very beginning of a file - tools likecss-loadermove@importat-rules above it, so it ended up in the middle of the generated CSS and broke the rule after it. Source maps are shifted accordingly. (by @alexander-akait in #1337)
