 Dear WordPress experts,

 We are experiencing a weird behavior preventing to edit tags / categories
 and publishing / updating posts. We believe it occurs when
 ''global_terms_enabled'' is ''on'' and some tags and categories share the
 same value.

 Our environment:
 * WordPress Multisite 5.1.1 (actually, we've been using it and upgrading
 it for years and years)
 * Table ''sitecategories'' defined
 * In table ''sitemeta'', ''global_terms_enabled'' is set to ''1''

 Steps to reproduce:
 * Create a new category "My category" THEN
 * Create a new tag "My tag" THEN
 * Create a new category with the same name of an existing tag, let's say
 "My tag" THEN
 * Create a new tag with the same name of an existing category, let's say
 "My category"

 Now it will break if you do the following:
 * Edit the category "My tag" with the name of an existing tag, you'll get
 "You need a higher level of permission. Sorry, you are not allowed to edit
 this item."
 * Edit the tag "My category" with the name of an existing category, you'll
 get "You need a higher level of permission. Sorry, you are not allowed to
 edit this item."
 * Create / edit a content and assign the category "My tag" (with the name
 of an existing tag) or assign the tag "My category" (with the name of an
 existing category) and you'll get a 403 error with the response
 {{{
 {"code":"rest_cannot_assign_term","message":"Sorry, you are not allowed to
 assign the provided terms.","data":{"status":403}}
 }}}

 May be related to #46297

 Thank you.

 Best regards.
