[DataGrid] Dynamic row height does not work with pinned columns

[kkapitanova]

I have searched the issues of this repository and believe that this is not a duplicate.

Summary 💡
I want to be able to have pinned columns and auto row height together. Currently, it seems that the getRowHeight={() => 'auto'} property behaves correctly only when there are no pinned columns.

Examples 🌈
Here is an example to showcase this: grid demo - StackBlitz

Steps to reproduce:

1. Click the ‘Add’ button to add more values in the array to see how the row increases its height (there are no pinned columns)
2. Click the ‘Delete All’ button to delete all of the values and see how the row decreases its height
3. Click on any column to pin it left/right
4. Go through steps 1 and 2 again and notice how the row height is not decreased when deleting the values

Motivation 🔦
I believe auto row height should work the same way when there are pinned columns

Dynamic row height does work with pinned columns, however, it needs a bit of customization when the content may have its height decreased after initialization. See the example in https://mui.com/x/react-data-grid/column-pinning/#usage-with-dynamic-row-height This is necessary because when there's no height calculated for the row, we let all cells freely expand vertically, then we take the maximum value and apply it to the other cells. When one cell has its height reduced, the cell from the pinned column still has the old height value so this value is used.

This workaround is not ideal as it leads to some pretty ugly re-rendering while resizing.
Is there any better solution?

No, there is no solution. To know the dynamic row height we need to wait until after the row has rendered. Updating the pinned columns takes another render cycle.

This might be solved by #10059 if we render all cells inside the same container.
