GlTokenSelector doesn't render token content in development build under Vue 3

From !4865 (comment 2683483902):

Okay, so this is definitely some kind of compiler thing. It's caused by the presence of this comment.

My guess is that in the production build, that comment is stripped out, so it doesn't interfere with the rendering of the token-content slot. In dev builds, it persists, and you can actually see it in the rendered DOM:

The presence of that comment node overrides the token-content slot's default content.
