I have a grid with several ForeignKeyColumns.
In IE11 when I click on a column the dropdown opens (for a blink) - the input moves a bit - and after that it works as expected.
I can also Tab through the fields - if I focus them first they move a bit (without opening) and after it they work normal.
In chrome the "initial moving and ''blink' opening" does not occur.
This only happens in IE when the column is to small to display the whole dropdown.
