fix: disable anchor default behavior

[xiaoyifang]

mostly fix #1379

With this PR ,the following dictionary will continue to load. In the same time ,the script will not work any more during page loading.
Users have to make sure that the script is executed until document ready.

such as (take #1379 for example)

window.load=function(){
document.querySelector("a")?.click()
}

Limitation: only fix the mdx dictionary which is mostly used and most probably customized with js by users.

Another solution is to modify the script and add the defer attribute .
<script src="" defer/>
