Custom Editor inside a listview disables on show

Hi,

I have a custom listview using custom viewcells having radio buttons and editor control inside it. On tapping the radio buttons the comment box visibility is toggled (show/hide).
On loading the listview for the first time the editor control visibility is by default hidden. Once the radio buttons are tapped, the editor is displayed. The issue here is that the editor disables when it is shown and no keyboard pops up on tapping it.

It works perfectly fine on Android and IOS versions till 10.3

I am facing this issue with all IOS devices having version 11 and above.

Xamarin Forms v2.5.0.91635

Please help.

Thanks,
