Trap focus key navigation in Select Range

[azmy60]

It probably makes more sense if we can always trap the focus when enabling Select Range, IMHO.

I often spam pressing arrow keys if not with ctrl to go to the side of the table. But since tabulator doesn't call .preventDefault at certain condition, it instead does something else to the page. For example, it scrolls the page instead of staying in position, and in my browser, it can go to the previous page (by pressing Ctrl+Left).

To replicate:

• Try pressing left/right/up/down repeatedly

This fix can be very helpful too especially if a browser or an app has a custom keybinding. In my browser, I use Ctrl+Left/Right for going to previous/next page. It's annoying that I often accidently change my page when I no longer can go left and I press Ctrl+Left.
