Can we get TD element for TD that is not rendered on the screen

When we were using getCell method in the newest version we encountered some problem.

We want to get TD element for TD that is not rendered on the screen so we can add a title attribute to this particular TD. We failed to do so, then we looked it up in the document, instead of solutions we found this:

Returns a TD element for the given row and column arguments, if it is rendered on screen.
Returns null if the TD is not rendered on screen (probably because that part of the table is not visible).

Are any workarounds? Or did we miss anything?

Only workaround is to render the cell, but you may encounter performance issues.
Here is an example https://jsfiddle.net/og3vr8h9/

I am using viewportColumnRenderingOffset and viewportRowRenderingOffset to render 200x200 matrix and then call the getCell method for a cell that is not visible.
