chatbubbles: memory overflow "exploit" (truncate display)

[Cynosphere]

chatbubbles can render a lot more characters than is needed, causing people to be able to overflow other players memory to the default heap allocation (3GB) if the attacker has a higher heap allocation

tldr: lots of characters = oom errors and possible crashes

I'm having the same problem with my overhead chat. Would love to see a fix for it here, as it would solve both of our problems
