Steps to reproduce the issue

Maybe I got it wrong here with "optionsStorage". I thought it's a mechanism to send logic data to the client side. So, I add my script options from inside my module to be used by the module's js. Everything works fine until I enable global cache and refresh the page.

Expected result

Expecting the script to appear in the head of the document.

Actual result

With the second load of the page with the cache on, the script isn't there anymore.

System information (as much as possible)

Tested on Joomla 3.7.3 and 3.8.7

Additional comments

Disabling the module from caching has no effect
