fix: forceNoGlow false on flyout blocks

For some reason, this wasn't getting respected anyway and flyout blocks
were glowing anyway. Now that we're using block glow to track project
run status, set forceNoGlow to false on the flyout blocks so that
clicking one still counts as making the project run, like it did before
the previous commit.
