Firefox - Clipboard has broken

[eddie-englund]

Recently copying cells has broken in Firefox. I'm not certain if it's a revogrid issue or a Firefox issue but nontheless I've started this issue to see if I can get some attention from other users if they're seeing the same problem.

If you select multiple rows or even a single row and press cmd + C (on mac) or ctrl + c to copy you will see this error::

This might relate to #399 but I'm not certain.
