TableView specific item drop target not visually showing drop highlight

[GrantRussell]

The TableView drop highlighting does not appear when attempting to drop over a specific item. I only see blue highlighting for drops when hovering over root, but none appear when I attempt to drop over a specific item.

This does not occur with other drag-and-drop components like ListView, even though we are passing the exact same drag-and-drop hooks. Here is a CodeSandbox link to reproduce the issue:

🤔 Expected Behavior?

When I hover over a target that accepts dropping, I would like to see blue highlighting to indicate the item will accept the drop.

😯 Current Behavior

No visual highlighting appears when I hover over a target that accepts dropping.

Additional context from @reidbarber:

the item drop events are occurring, the styles are being applied, and even the computed styles look right (so not a css specificity issue)

Just a quick initial look but it looks like this broke in v3.29 which is when we added expandable rows so it might be related to those changes.

Looks like this is due to no longer updating the background-color of the Table-cellWrapper elements when it the row is a drop target.

Looks like dropState is stale when used in renderWrapper: https://github.com/adobe/react-spectrum/blob/9e6513b9adc527e0926795e7e3361788ae860333/packages/%40react-spectrum/table/src/TableViewBase.tsx#L363
