Review Comment:
Sure, I will do the rename.
Let me explain the usage of that input with more detail. If there is a
better way to do so, please tell me.
In our project, we have a multi level dashboard(designed by user) and every
dashboard can scroll insides like the picture below.
Also, we want to manage all common tooltip config for different charts in a
single config file. And I cannot use `myChart.getDom()` in that config file. So
I need to have that element as an input such than I can use `e =>
e.closest('.scroll-container')` to locale my tooltip element correctly.
