[Yes] I have been able to replicate this

Nothing we can do about this, Dynmap isn't a chat plugin and just pulls from the "global" channel

The solution for this is via the API - as stated, we work with standard chat messages, as defined by the Spigot/Bukkit API, by default, but the API does have mechanisms to allow 3rd party plugins to override that behavior - https://github.com/webbukkit/Dynmap-HeroChat is an old, but still relevant, example of this. As a rule, we don't bake plugin support into Dynmap (only exception is permissions), but do try to enable plugins to work with a supported API - whether directly (WorldBorder directly uses our API) or indirectly, via 'linking' plugins, like Dynmap-WorldGuard or the like
