Alignment of placeholders is always at the left

[joulev]

This Codesandbox is a fork of the placeholder example on the website. I simply added the align plugin

createAlignPlugin({ inject: { props: { validTypes: [ELEMENT_H1] } } }),

and set the hh1 in the initialValue to align="center".

As you see, while the h1 is indeed centered when I type to it, the placeholder is not. I want the placeholder to also follow the element's alignment (left-center-right-justify) as well, how should I do that?

Not sure if the behaviour in the CodeSandbox is intended, so I chose to ask this question instead of opening an issue – please tell if I should go to the issue tracker instead.
