研究方向
The bug is in the Less CSS preprocessor's parsing of @container style queries, where an unintended space is added between 'style' and the opening parenthesis. To fix, inspect the parser code responsible for handling the @container directive and the style() function. Look for tokenization rules that might insert a space. Check the Less source code in the 'lib/less/parser' directory for the relevant grammar rule. The issue has been discussed in the comments; review any proposed solutions or pointers from maintainers. The fix should ensure that the parser does not add a space after 'style' within @container queries.
