[DataGrid] Keyboard shortcut to select a row (Shift+Space) not working

[wouter-leistra]

• The issue is present in the latest release.
• I have searched the issues of this repository and believe that this is not a duplicate.

Current Behavior 😯

Datagrid renders and a cell has tab focus, using the shortcut SHIFT+SPACE as per docs to select the row, results in nothing to happen. Tested on latest Chrome and Firefox releases.

Expected Behavior 🤔

The row of the cell that had focus after using the shortcut is selected.

Steps to Reproduce 🕹

Hi, @wouter-leistra thanks for catching this. I tested it, it is also reproducible on the MUI website.

That's a regression

• We document the shortcut in https://material-ui.com/components/data-grid/accessibility/#selection
• The regression happened between v4.0.0-alpha.14 (working) and v4.0.0-alpha.15 (broken)
• The regression happened in [DataGrid] Fix keyboard event collisions #794
