Bug w/ not loading block themes default styling

I’ve noticed a bug that when using spectra with block themes that some of the default block theme css wont load automatically for the spectra blocks.

For example: The spectra buttons wont include the block theme button styling unless there is a vanilla wordpress button somewhere on the page to load in the css.

The only way I’ve been able to get around it is include a vanilla button block in the header & just hide it.
