config for leaving URL fragment unchanged

[fortm]

If base URL is as below -
http://localhost/project/module#fragment_key=fragment_value

the plugin adds # to end of URL when click event occurs on mainButtonClass="mfb-component__button--main" and URL becomes as below -
http://localhost/project/module#

So the fragment_key and fragment_value is removed. I am opening a modal on click for menu item and would ideally have the URL unchanged so that when modal closes the fragment in URL don't change as the page has not changed

Is this possible that clicking on menu button / menu item does not lead to displacement of exisiting URL fragment in favour of "#" ?

<a> tag without href helps for menu button

 <a  class="mfb-component__button--main">
                  <i class="mfb-component__main-icon--resting ion-navicon-round"></i>
                  <i class="mfb-component__main-icon--active ion-navicon-round"></i>
</a>

Have href="javascript:;" and it wont add the '#' to the end of the url!

<a href="javascript:;" class="mfb-component__button--main main-btn">
          <i class="mfb-component__main-icon--resting ion-plus-round"></i>
          <i class="mfb-component__main-icon--active ion-close-round"></i>
</a>
