Cell Context menu event should maintain the cell selection when triggered within the selection

[seancolsen]

Steps to reproduce

1. Select a block of cells.
2. Trigger the context menu on a cell outside the selected block.
3. Observe the cell selection to change, selecting only the cell on which the context menu was triggered. (good)
4. Select a block of cells again.
5. Trigger the context menu on a cell inside the selected block.
6. Expect the cell selection to remain unchanged when the context menu opens.
7. Observe the cell selection to change, selecting only the cell on which the context menu was triggered. (bad)

When the context menu opens on a block of selected cells, it should contain only one entry — an entry to "Delete Records" (which should delete all selected records). We already have this "delete multiple records" functionality built into the table inspector under the "Record" tab.

@seancolsen I had a question on this issue:

Since we do not have any action in the context menu as of now that works on multiple cells together, what is that menu supposed to show?

@rajatvijay that's a really good point. Thanks for raising this. After giving it some more thought, I think we should draft this issue until the point when we do have context menu actions that can operate on multiple cells.

@monstajoe2002 you can find another issue to work on if you like

Now that we have the ability to delete multiple records at once, I'm marking this ticket as ready, and I've updated the description to specify the content of the context menu when opened on multiple cells.
