Using slash commands does not mark messages as read

[asportnoy]

Description

If you have unread messages in a channel, using a slash command does not cause them to be marked as read.

I originally submitted this in the Discord server as an idea, but was told to submit here as a bug by @msciotti

Steps to Reproduce

Have unread messages in a channel and use any slash command

Expected Behavior

The unread messages get marked as read, just like if you had sent a normal message

Current Behavior

They are not marked as read
