I'm facing this issue as well. Is there any workaround to rerender ResourceItem without unselecting it?

[loic-d]

We are currently re-rendering by updating the key prop on the element.

+1 can't believe this isn't solved yet

Edit: Solved this by using Ioic-d idea of changing the key prop.
To change the key prop just define it like key={changableVarible && index} .
In case you guys have multiple changing variables key={[changableVarible1,changableVarible2,index]} will work. Good luck!
