Hi,

It appears that a long-standing issue in the PowerShell highlighting grammar is the cause of this.

The extension's built-in (but experimental) semantic highlighting does support enum correctly. You can follow the instructions here to enable that, but it was disabled by default while its stability is improved.

Thanks for the bug report. I'm going to transfer over to the relevant repo.
