Regular members listed as owners in channel members list

Description:

The members on channel list are mentioned under Owners moniker when they are just users, and vice versa.

Actual roles work ok, so this is a cosmetic but confusing error in the channel members list.

This has been around for at least since RC 7.8.x when we noticed it, but I hadn't just reported it earlier.
We don't know what triggers this issue.

Steps to reproduce:

1. (Not known what triggers this issue)
2. Go to channel where you are an owner
3. Check the members list, pay attention to your mentioned status in it, and check your members management menu

Expected behavior:

Owners are sorted correctly as owners in the members list.

Actual behavior:

Real owner is marked as a regular member. Random regular member is shown as an owner.

These "fake owners" do not have real ownership options in their menus either, nor do they have badge in their messages.

The real owner has an option to remove and promote owners as usual. The real owner Toni Härkönen (in the picture) checking the menu on himself.

Additional context

Promoting members as owners or demoting owners back to members on the channel temporarily fixes the members view issue. But refreshing the RC window breaks the sorting again.

No source file or test is identified. Start by reproducing the issue in a channel's members list, comparing owner and regular-member roles before and after refreshing the Rocket.Chat window; done means the displayed owner labels remain correct and match the available management options.
