Code looks good at first sight but I noticed some problems when trying it out:

• Session List "Active People" is not shown anymore
• Emoji Picker menubar entry has no tooltip and funny color on dark background
• edit guest user name also has color issues on dark background.

I'm not sure if the funny colors are related or not. Will try with current master and provide screen shots.

Missing title in session list

Before:	Now:

Current Markup (notice data-original-title):

Funny color, no tooltip in emoji picker

Funny colors in guest name - tooltip is fine

[max-nextcloud]

Funny color in guest name entry also exists on stable28. So not caused by this.

@luka-nextcloud did you test the image insertion, active people and link picker?
They still don't show for me.
I checked out the branch, booted the nextcloud-docker-dev for server master, compiled the js and checked there.

@max-nextcloud I have just checked again. It works well:
