Description
The performance of the Grid block when in Manual mode (and probably also Auto mode) is bad.
You particularly notice that the UI is slow to react to mouse events after the editor has been running for a while, so there's probably some memory leaking.
I can also see that all the components in GridVisualizer are updating on every keystroke which isn't good. An easy win might be to memo() every cell. We are probably over-useSelecting data in a lot of places too.

Let's spend some time tuning this before shipping.
