How to prevent wrong documentation popup for javascipt in html files ?

Hi all I have found a confusing problem when using IntelliJ idea.

Open a html file , move mouse cursor around js codes, then a documentation popup will easily and frequently show up, which contains no useful infomation , and it will show up itself even when the mouse cursor is hovering on blank area of the javascipt code block. 

here is it's content : 

script

------------------------------------------------------------
The HTML <script> element is used to embed or reference executable code; this is typically used to embed or refer to JavaScript code.
