Bulk edit should only display available post formats

[eightface]

Currently, the the bulk editor will display all possible post formats. It should probably only show the ones specified by the theme, to prevent weird things from happening.

Hello eightface, thanks for the report and the patch.

I think this is a valid bug and we should make it consistent with post_format_meta_box().

Patch looks good so far. Only some minor things:

• <option value="standard">Standard</option> should be <option value="0"><?php echo get_post_format_string( 'standard' ); ?></option>
• Since we're showing only theme supported formats a current_theme_supports( 'post-formats' ) check should be added.

Use 0 for standard option value, check if theme supports post-formats

[eightface]

Use function to get standard post format title

Thanks! First time submitting a ticket/patch. Not as terrifying as it seemed. Admittedly the UI changes here have made it a lot friendlier.

Replying to ocean90:

Since we're showing only theme supported formats a current_theme_supports( 'post-formats' ) check should be added.

My initial thought was that if the current theme doesn't support post formats, we should still be able to change the format to Standard. However, the Format meta box currently has the same check, so this would be consistent.

27187.3.diff​ looks good to me.

In 27762:

The bulk editor and post format meta box should use the same checks for available post formats.

Props eightface.
Fixes #27187.
