Issuable Sidebar Collapses After Interaction

Summary

Opening the issue sidebar by clicking the action icons causes normal sidebar interaction to collapse the sidebar.

Steps to reproduce

1. Open an issue
2. Open the sidebar by clicking on an action icon (like label)
3. Click the edit button on a different section (like milestone)

Expected behavior

The sidebar should stay open.

The sidebar should collapse and no inner sections should open.

Actual behavior

The sidebar collapses with some of the sidebar content in an active state.

Possible fixes

There is probably some state that is being flipped when the open button is clicked, but is not flipped when the other icons open the sidebar.

This can probably be fixed by centralizing sidebar toggling logic that opens the sidebar into a single method that can be reused.
