The API auto-detects two parameters: state, which is fine, and !}} style="border-spacing:1px;display:block;overflow:auto;width:100%;margin:0 !important"\n{{!}}- style="line-height:125%; vertical-align:top;"\n! style="text-align:right; width:3%; background:transparent" {{!}}. Yes, that's reported as the parameter name.
Detailed analysis
It is entirely impossible to use these sequences in a parameter name:
- | separates different parameters. There is no way to escape this or any of the following in a parameter name.
- = ends a parameter's name, and starts the value. At least when calling a template. The situation here is a little weird. It appears like attempting to use a parameter like {{{a=b}}} in a template is valid syntax. But it's (almost, see below) impossible to call this parameter. Attempting to do so will create bad wikitext that calls a parameter a instead of a=b.
- {{ and {{{ start another syntax element, and }} and }}} end one.
It appears like it's technically possible to use the following sequences in a parameter name:
- Single { and }.
- \n, i.e. the parameter name is a multi-line string.
However, this is extremely unlikely. We can pretty much guarantee there is something weird going on. Either the auto-detection made a mistake. Or the template is just broken. No sane template programmer would ever use curly braces in a parameter name. They would be constantly confused with syntax. Same with newlines in the middle of a parameter name. I have never seen anything like that in the 15+ years I deal with wikitext. And I touched a lot of templates, from a lot of users. Let's assume these are errors and not offer them as auto-detected parameters.
