Missing Center-Alignment for Headings and Images with Gutenberg

[ianstewart]

A few of our free themes are missing center-alignment for headings and images.

Twenty Nineteen has offset headings when they're center-aligned.

Sketch does not correctly center-align images. Neither does Franklin.

Thanks for tracking it down, @ianstewart

Twenty Nineteen needs a patch in core to fix those headers. I've created one here: https://core.trac.wordpress.org/ticket/49699

As for Sketch and Franklin, I've tested these on my end and I'm only able to consistently recreate in the editor, and only when I follow the following steps:

1. Add an image.
2. Resize it to be a custom size using the handles or the sidebar.
3. Set the image to be center-aligned.

This appears to be a general Gutenberg bug, since I see it in all themes. I've filed a bug here: WordPress/gutenberg#21152

Otherwise, images appear to be center-aligned just fine:

Is there something I should do differently to reproduce?

Is there something I should do differently to reproduce?

Huh. Strange. Could be related to the preview method I used?

I ran a few tests with both Sketch and Franklin but I can no longer reproduce this so I am going to close this issue.
