Multiple dashes in post slugs where title contains a dash surrounded by spaces

[andizer]

I am not sure if there is already a ticket. I've searched for it and haven't found any tickets. The issue I've got is about a new post where the title contains dashes surrounded by spaces. These spaces are also replaced by dashed in the generated post slug. For example: Korn - Freak on a Leash title will be converted to korn---freak--on-a-leash.

I can't reproduce. Did you try with standard theme and all plugins disabled?

I also can't reproduce same issue in WordPress 5.3-alpha-45524

It only happens when you save the post as a draft. In the collapsible with permalink the slug contains the double dashes. When publishing the post it seems the double dashes are removed.

Now I see, entering as title:

I'm just a - Test -- yes - - - a test

gives the example like on the screenshot.

It's the same issue as in #45478 and #46088.

The slug is generated client side, which doesn't have an equivalent of sanitize_title().

Going to close in favour of GB12907, as it needs to be handled in the block editor JS.
