WhiteBoard in add delete multiple tabs
Hi All,

First of all, Thanks to the developers team for creating this awesome library.

Actually, I was trying to create a whiteboard application.. in which I can switch between multiple tabs and create and delete tabs too..
But I'm facing some issue. When I try to switch between tabs.. it's not considering the props of whiteboard in the second tab.. 

I'm sharing the demo in codesandbox for reference. Please correct me, where I'm doing mistake.

I just want to have the multiple tabs where my multiple whiteboards can switch, and my previous whiteboard drawing will also exists.

Please help me to come out of this. Thanks in advance.
