  Log Message:
  -----------
  [WebGPU] Debug assertion in RenderBundleEncoder::currentRenderCommand() fails when RenderBundle has zero commands
https://bugs.webkit.org/show_bug.cgi?id=279693
radar://135708146

Reviewed by Tadeu Zagallo.

When commandCount is zero, we would replay the first recorded operation
when that was not needed, triggering the debug assertion in currentRenderCommand()
