IN Reply - remove "x" button NOT WORKING
When reply or reply all, the senders and recipients auto populated in TO and CC cannot be removed.
The remove "x" button is there but clicking does not do anything.
If you add new recipients, those can be removed by clicking "x"
Something is wrong with the auto populated To and CC
