Those are the steps to move the flag:
1. open menu;
2. click move up - `saving` CSS class is added;
3. request to backend;
4. `saving` CSS class is removed.
To check if the action was finished we are using this method:
```
def move_up(key)
open_flag_menu(key)
find(".admin-flag-item__move-up").click
has_saved_flag?(key)
self
end
def has_saved_flag?(key)
has_css?(".admin-flag-item.#{key}.saving")
has_no_css?(".admin-flag-item.#{key}.saving")
end
```
However, sometimes specs were failing with `expected to find CSS ".admin-flag-item.spam.saving" but there were no matches`
I think that the problem is with those 2 lines:
```
find(".admin-flag-item__move-up").click
has_closed_flag_menu?
```
If the save action is very fast, then the `saving` class is removed before the first check.
Therefore, to determine that the move action is finished, I am checking if the menu is closed.
* `@ember/owner` instead of `@ember/application`
* `discourse-i18n` instead of `I18n`
* `{ service } from "@ember/service"` instead of `inject as service`
Before checking if flags were reordered on the topic page, we need to ensure that the reorder action was finished. To achieve it "saving" CSS is added and removed when AJAX call is completed.
Continued work on moderate flags UI.
In this PR admins are allowed to change the order of flags. The notify user flag is always on top but all other flags can be moved.
