Hello,

I am using tooltip component for a long desciption field in my grid cell. And I am using it as it will encapsulate Grid component (like the example below) as it is suggested in this page.

<Tooltip openDelay={100} position="right" anchorElement="element"> <Grid>... </Grid> </Tooltip>

My grid has a date field and I am using columnMenu for filtering (GridColumnMenuFilter). An error occurs when I hover the text of date field and says : 

Tooltip(...): Nothing was returned from render. This usually means a return statement is missing. Or, to render nothing, return null.

I also trid to replicate the problem in the example on this page and it gives the same error. I forked the project and you can check it from https://react-ed5jns.stackblitz.io/

Simply move the cursor over month/day/year in a date filter area and see the problem. This seems like a bug. Or if there is any solution to this, I would like to see a workaround.

Thanks
