Summary0002885: Fails to build when compiled with -Werror=calloc-transposed-args
DescriptionWhen build libcss with -Werror=calloc-transposed-args, I get the following error:

src/select/computed.c: In function 'css__computed_style_create':
src/select/computed.c:76:27: error: 'calloc' sizes specified with 'sizeof' in the earlier argument and not in the later argument [-Werror=calloc-transposed-args]
   76 | s = calloc(sizeof(css_computed_style), 1);
      | ^~~~~~~~~~~~~~~~~~
src/select/computed.c:76:27: note: earlier argument should specify number of elements, later size of each element
