I have listed steps to reproduce the bug in detail.

Expected Behavior

some md text need to be convert to latex.

const md = '\\(\\xi = (\\xi_1, \\dots, \\xi_N)\\)'; // this  can convert to latex 
const md2 = '\\(\\xi = (\\xi_1, \\dots, \\xi_N)\\)xx'; // this  can not convert to latex

also I see the source code.

this file will detect the latex text and it can not detect the md text. But I dont know how to fix it. The test code can test in katex-extension.ts

const { inlineRule, blockRule } = generateRegexRules(DELIMITER_LIST);
console.log('inlineRule: ', inlineRule);

const md = '\\(\\xi = (\\xi_1, \\dots, \\xi_N)\\)xx';
const aa = md.match(inlineRule);
console.log('aa: ', aa);```
