Add category from editor produces some weirdness when adding subcategories?

[Denis-de-Bernardy]

While testing WP 2.7, I tried the Add Category link in the post editor. I had two cats in there (Blog, cat). Upon adding cat2, a subcategory of cat, I ended up with Blog listed twice.

some more weirdness on this one. apparently, some bug will make the subcategory list lie flat in some circumstances. attaching screenshots of new post and test post to show the error

new post (subcategories look normal)

test post (subcategories lie flat)

seems quickedit is affected by screen-capture-1.png too

also mentioned here #8632

see also: #9391

attached patch will move checked categories if and only if they've no parents.

see also #3130, which describes what seems like the best approach.

patch needs a refresh

Fix. Do not commit.

• complete mess in 2.8 trunk on current test.

• function wp_category_checklist() is missing a propper docblock.

• class Walker_Category_Checklist is missing propper description everywhere.

• patch has been somehow transposed. that did not make no sense.

fix in patch: remove the functionality to put seleted categories on top. should give enough space to re-write the patch on current trunk.

fix seems to be ready to commit because Selected categories should always be at top has been closed as wontfix. see #3104. or you see #3130 (#7000 is dup) which is an assigned enhancement and set to 2.9.

so please patch the bogus functionality out of the trunk and close the ticket. #3130 should then lead the way then.
