Page Operations Menu display can be too long for low-resolution settings

Issue Summary

If the resolution of a device is set very low, when viewing a page, the '...' (Page Operations Menu) can be too long, and it is not possible to scroll all the way to the end.

Steps to Reproduce

1. Open a Confluence page in your browser. It should be a very short page, with only 1 line of text perhaps.
2. Re-size the browser window to be quite short - less than 600pixels
3. Click the '...' menu on a Confluence page

Expected Results

The menu would be scrollable and all options would be visible

Actual Results

The menu is too long to display on screen, but you cannot scroll down to the bottom options.

Workaround

In Confluence, go to the 'Stylesheet', and edit the 'Global Stylesheet' to contain the following:

#action-menu {
    overflow: auto;
    max-height: 250px;
} 

You can play with the max-height setting to be bigger or smaller, depending on what resolution you need it to work on.  This will force the menu to be much shorter in height, but it will be scrollable.

If you don't see any differences after setting the custom CSS on the Stylesheets page, attempt the following steps instead:

1. Remove the custom CSS from the Stylesheets page
2. Go to General Configuration > Custom HTML and insert the following code in the At end of the HEAD textbox:

   <style type="text/css">
       #action-menu {  
       overflow: auto;  
       max-height: 250px;  
       }
   </style>
   

3. Save and test the results
