Kernel selection on cells are overwritten when copied to a new notebook

[sharoncxu]

Describe the bug

I am copying cells from one notebook to another. The kernel selection on those cells are automatically changed to be the default kernel of the second notebook. I have to go through and manually change in the selection on every cell which is quite tedious.

E.g. when I copy python and JS cells to another notebook that has C# as the default language, all the cells become C# cells
