This sounds like a OS issue to me and not something VSCode could produce. I have not seen this.

@fourcels does it make a difference if you run "code" from the command line?

Just throwing my hat in to say I'm experiencing this too - every time when running code from the command line. It seems that Mojave treats this invocation as a new application instead of recognizing it as already being in the dock. I believe this could be an issue in the code shell script as opening other applications from the command line does not cause this behavior.

Note: this is related to the new "Recent Items" feature of the Dock thus why it only occurs in Mojave

If someone has ideas...

Looked into this a bit deeper. Calling the executable of any application from the terminal while that application is already running will result in the observed behavior, even for stock macOS apps. The solution would seem to be to rewrite code.sh so that it opens VSCode without calling the application executable or hope it gets patched in a future macOS version.

The former should be possible as Sublime Text's similar subl command does not exhibit the behavior.
