When a link is at the end of a line (e.g. @ link to another project), click after the link, the caret is now positioned at the end of the line after the link. Typing a space or any other character I've tried extends the link. I'd expect a space to break out of the link so normal (unlinked) text can be added. The only way I've found to add unlinked text after an end-of-line link is by copy pasting some normal text.
