Steps to reproduce:
- Go to Admin / Content structure.
- Create new 'Landing page' content.
- Being on block configuration page, click on 'Timeline' button.
After extending the "Timeline" functionality, the first element of the right menu is partially obscured.
Elements of right menu shouldn't be obscured by 'Timeline' functionality.
