Issue Summary

If a Page has the Attachments Macro in its body, it won't be possible to add an Advanced Roadmaps for Jira plan Macro as the menu is cut off.

Steps to Reproduce

1. Create a new Page (or use an existing one)
2. Add the Attachments Macro (using the '+' Insert button or by typing '/attachments')
3. Add the Advanced Roadmaps for Jira plan Macro
4. Notice the menu is cut off and the Macro cannot be added

Expected Results

The menu for Advanced Roadmaps for Jira plan Macro is centered when adding it to a Page.

Actual Results

The menu is cut off and hides the URL field, which prevents the Macro from being inserted.

PS: neither scrolling nor zooming out helps here.

It seems like the offsetTop parameter is being set to 0 instead of a value, so the menu is stuck to the top and visibility is blocked.

Workaround

Steps:

1. Temporarily remove all Attachments Macros included on the Page
2. Include the Advanced Roadmaps for Jira plan Macro
3. Re-add the Attachments Macros
