After clicking "Block" auto load the next email without making me click email pane

Expected behavior

On the left sidebar, upon selecting an email, there are two choices: DELETE and ACCEPT. After choosing DELETE, I want to resume reading by automatically loading the next email without wasting time.

Actual behavior

On the left sidebar, upon selecting an email, there are two choices: DELETE and ACCEPT. After choosing DELETE, I need to click on the left sidebar email pane once more to continue browsing through emails or chats.

what is the next email? the next unread contact request?
