Possible Bug: DataGrid Frozen Columns First Column Width In rem

I have a DataGrid where I have frozen the first two columns. The second column would appear too far to the right and overlap part of the third column. The first column is narrow with a Width="3rem" and the browser DevTools show the second column with a left value = 200. It took me a bit to figure it out. The first two image below show the problem reproduced from the demos. The code in the image at the bottom seems to be the problem. I have no idea if this is a bug or if this is the way it was meant to be. Using px solves the problem.

Yes, at the moment only pixels are supported, still you can submit pull request with support for rem.
