Forum: can't type anything if you start with a "mention" aka "@<person name>"

[Trufir]

When you start typing with @ mention to any person and complete it, cursor focus gets locked within that input and you can't break out or type anything else anymore.
You are even stuck with it trying to refresh and only when you "ctrl + A" "delete" it at refresh you can type again as long you type some text first before putting a mention in.
