[data grid] filter and columns poppers incorrectly positioned when using a toolbar

[jcrang]

Steps to reproduce

Link to live example: (required)
https://codesandbox.io/p/sandbox/relaxed-frost-vsxqk5?file=%2Fsrc%2FDemo.tsx

Steps:

1. Click "Columns" or "Filters"

Note: this only occurs when using a toolbar. Poppers are correctly positioned when not using a toolbar.

Current behavior

Position of popper obscures headers

Expected behavior

Position of popper is below headers (as in MUI X 6):

Hey @jcrang
Thanks for raising this.
It is happening due to a change in the layout.

The fix would be a rather easy one, so I am opening it up as a good first issue.
