Merge branch 'issue-boards-dragging-fix' into 'master'

Fixed dragging issues on issue boards

## What does this MR do?

This fixes a few issues all at once:

- Fixes an issue when dragging an issue to a list but actually removes another issue from the original list
- Fixes an issue that caused the issue card to be appended to the bottom of the list
- Fixes an issue when dragging an issue would actually open up the sidebar

## What are the relevant issue numbers?

Closes #24654

See merge request !7701
