I want to remind that this extension still conflicts with the Profile Cover from @SychO.
f you install the cover using Profile Cover without installing Decoration Store, then everything works fine, but if you install the cover using Profile Cover with the Decoration Store enabled, then the cover and avatar will start flashing, and the background appears and disappears for a moment when switching profile tabs.
Most likely this is due to the rendering of the profile block, because both extensions have this functionality, but I do not know how to disable it from the Decoration Store so that only Profile Cover affects the background. This indicates a conflict of styles or reactive updates between these extensions.
I recorded a video with an error. @luceos I don't see a link to the extension's github to save the error. Is there no other way to notify the author?
