Update: This has now been released so new line characters are now respected and persisted in the grid
Targeting end of July, we are enhancing the UX grid so that new line characters are now supported. Any new line characters that are currently in the grid will now be visible. If you do have a new line character that is currently hidden in the grid following the update it will be added, which means in these examples the text will shift down to the next line. On single row height grids this will move the data out of view, for multi-line grid heights the text will be visible on the subsequent row.
Note: This will not change the grid row height behaviour. This will still need to be set by a Page Builder in design mode.
