textarea as grid editor renders behind grid header

Hi, I tried searching for this issue to no avail...



I'm using Ext 5.1, and have configured a textarea as the editor for a grid column. When using the editor in the first row of the grid, when the user clicks the textarea and it expands, the textarea is stuck behind the grid header.



I tried configuring toFrontOnShow on the textarea, and messing with the z-index with css and neither of these worked for me.



Anyone have any recommendations?



Much appreciated,

Ed
