Delete Icon not visible on Email in Timeline

Hi,

Timeline now shows reply, reply all and forward icons for Email, the delete icon is not present. This looks like a recent update with the Wave 2 release.

This is only in case of Email, for task and appointment the delete and assign icons are present.

Also, it is not visible for system administrator, Opening the record and deleting it worked.

Let me know if we can get the Delete Icon back for Email on Timeline Control.

Any help is appreciated, Thanks in advance!
