Selecting, deleting and creating rows don't work as it should

Issue found

• Selecting existing rows does not work every time I click on the row number.
• Deleting rows seem to be impossible when rows deleted are in the bottom, until I create a new row.
• Creation of rows works every now and then.
• Snapshot: 186
• MacOS, M1

How to reproduce

1. Take the latest snapshot
2. Open Model editor from view menu
3. Create a model
4. Create some columns
5. Create a few rows
6. Delete some rows until you delete the last in the bottom. See the video:
   RowDeleteFails.mp4
7. Now you can't select a row anymore, until you add a row - then you can.
8. Clicking on a cell, and creating rows above or below works randomly. Works sometimes. See the video:

How it is expected to work

• The whole row selection should happen when the row number is clicked.
• Finding the click target should be easy (now it requires multiple clicks to find it) for both row and cell
• The user should be able to add rows above or below, when a cell is selected
• Deleting a row should be possible when a row or a cell is selected
