If it isn't providing a "function" then it would be ok - or if the same 
"function" were available in another way then yes it would be ok. F54 
talks about being the only means to invoke the scripting function. If 
the scripting function is to display some information then so long as 
there is another way to display this information this would be ok.

2.1.1 talks about functionality of the content where functionality is 
"processes 
<https://www.w3.org/TR/2008/REC-WCAG20-20081211/#processdef>and outcomes 
achievable through user action" and processes are "

series of user actions where each action is required in order to 
complete an activity

/Example 1:/Successful use of a series of Web pages on a shopping site 
requires users to view alternative products, prices and offers, select 
products, submit an order, provide shipping information and provide 
payment information.

/Example 2:/An account registration page requires successful completion 
of a Turing test before the registration form can be accessed."


If the content provided by hover is provided in another way then the 
processes and the outcomes are achievable through user action.
