When placing text directly at the start of the chat input aka the "T" menu and without the ? modifier, it does not auto replace, I assume that there is a character behind the scenes that is preventing this from working.
It works just fine if I hit spacebar before I put any text in so there is a space between whatever character is preventing this and the text I want to be replaced
I'm not specifically saying this is a bug, it just would help a load to know what character (if one) is causing this so I can add it to the ? modifier
