Category not updating on bulk edit post

[jagatkri]

when we do bulk edit post and checked multiple categories. It will updated categories in bulk edited post. but when we unchecked some category then will not remove that unchecked category from post.

The issue seems to stem from the code base running an array_merge for every post being updated that combines it's pre-update categories with any new categories selected in the bulk edit panel. This creates a situation in which the bulk edit can only ever add categories to posts and will never remove a category.

By preventing this array_merge the bulk edit panel treats every post as a blank canvas and adds only the categories selected during the edit process.

Visually this falls in line with user expectations as all the categories are unchecked by default when a user goes to bulk edit posts.
