Fix boards top position on sidebars
What does this MR do?
This MR leverages MutationObserver to calculate the header height from top for boards setting sidebar and issue sidebar on boards.
The reason we needed a mutation observer was because there was a race condition on the performance header showing up on load.
Repro
- Go to a group/project issue board or group -> Epic board.
- on the keyboard, type
p+b - Click on an issue/epic card OR list settings button.
- Check the distance from the top from the header to the sidebar and make sure its flush against the header
