Dynamic preview head not rendering

[stuartizon-x]

Not sure if I've misunderstood this feature, but I've tried to add the new previewHead config option (#13432) and it seems to not be doing anything.

I've created a small sample repo here based on the way it's described in the docs. https://github.com/stuartizon-x/storybook-example.

I'd expect to see the yellow background I've added to the previewHead, or at least the added preview markup inside the DOM.

Turns out the presets got renamed to xTemplate (e.g. previewHeadTemplate) in commit 2a5895c

I tested out previewHeadTemplate in your repro and it's working as expected.

I'll discuss the change with @ndelangen to see whether we need to update the documentation or revert the changes. Thanks for raising the issue & sorry for the confusion!

Ah good to know I'm not a complete idiot! Thanks

ZOMG!! I just released https://github.com/storybookjs/storybook/releases/tag/v6.2.5 containing PR #14500 that references this issue. Upgrade today to the @latest NPM tag to try it out!
