filling/dragging to down does not work

[giorgiPapava]

Describe the bug

I installed the library from NPM, rendered DataGrid component with some mock columns and rows and onFill function. Drag identicator is visible but when I'm starting to drag it it's not following the cursor.

To Reproduce

1. npm install react-data-grid
2. render DataGrid component
3. drag any column

Link to code example:

Expected behavior It should start dragging the rows, but it does nothing, it only shows dragging indecator and doing nothing when I start dragging it.

Environment

• react-data-grid version: ^v7.0.0-beta.7
• react/react-dom version: "^17.0.1
