Kanban board: Incorrect focus order

Issue Summary

On Kanban board, Incorrect focus order observed in detail view. 

Steps to Reproduce

1. Navigate to Kanban board.
2. click on any issue to open detail view.
3. Navigate with tab key through detail view.
4. Observe that after comments "Add a comment" button receives focus inappropriately.

Actual Results

When user navigate through the issue detail view via tab key, after comments the focus moves directly to "Add a comment" button instead of "Attachment". 

This is because although DOM order of "Add a comment" section is correct but using CSS it is positioned at the bottom of the page.

This illogical tabbing order will create confusion for keyboard-only users.

Expected Results

The focus order of the elements should be as per the visual order on the page. 

Here after comments the focus should move to "Attachment", "Sub-taks", etc as per visual order of elements. 

This can be achieved with placing the code of the "Add a comment" section at the end of the DOM.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
