I noticed edit conflict indicators on various topics when I tried to edit them:
I think this happens when a tag that is not visible to the user was added while there is also a visible tag.
I can reproduce with the following steps:
- Use a test user to create a new topic and post the new topic.
- Use an admin (or another user with permission to add tags) and add at least one tag to the topic that is not in a tag group with limited visibility and at least one tag that the test user cannot see. Save the changes.
- As the test user, go to your topic, click the pencil to edit, and add a new line to the body.
Expected result: No edit conflict, as no one else is currently editing the topic.
Actual result: The conflict indicator is shown.
Additional note: It does not matter who adds the visible tag. For example, it also works when the test user adds it before creating the topic.
Will fix.
