Issue Summary

Opening the Roadmap Planner macro's edit dialog when Team Calendars is disabled wipes all previously saved bars from the editor. The roadmap renders correctly in page view and editor, but the content disappears in the macro's editor dialog.

The same underlying gap is expected to affect the Confluence Previews annotation feature, which relies on the same shared front-end interaction library.

Steps to Reproduce

1. Install a fresh Confluence instance.
2. Create a new page and insert the Roadmap Planner macro.
3. Add one or more bars to the roadmap, then save the page.
4. Disable the Team Calendars for Confluence app (⚙️ > Manage apps > filter to All apps > Team Calendars for Confluence > Disable).
5. Open the page in the editor again.
6. Click the Roadmap Planner macro, then click edit to open the macro's edit dialog.

Expected Results

The macro edit dialog opens and displays all previously saved bars, allowing them to be moved, resized, and edited normally.

Actual Results

The macro edit dialog opens blank, with no existing bars shown:

Adding new bars causes them to stack. The browser JavaScript console shows:

Uncaught TypeError: this.$el.resizable is not a function

Workaround

1. Enable the built-in Team Calendars for Confluence app (⚙️ > Manage apps > filter to All apps > Team Calendars for Confluence > Enable).
2. Reload the affected page.

Team Calendars has been bundled with Confluence since 7.11, so it is safe to treat it as enabled by default. Re-enabling it restores the interaction library that the macro editor depends on.
