Description

Making selections in the "Skin" or "Hair" tab of the avatar edit modal can cause not-yet-purchased items to disappear and reappear, with no particular rhyme or reason to when. Video: http://citrusella-flugpucker.tumblr.com/private/172581599183/tumblr_p6neomY0x01rl47k3

Doesn't only affect skins--saw this happen just now with hair colors, too. Updated.

This issue is still happening as of this date.

I saw a "hide" class on those "not-yet-purchased" that disappears. I'm new so I don't know what triggers that.

I can take this. Let me know

Go for it, @harumhl!

My finding so far is that in 'website/client/src/mixins/avatarEditUtilities.js', hideSet() occasionally returns true for some items (like 0.5% of the time) from moment(appearanceSets[setKey].availableUntil).isBefore(moment()), thus hiding those items momentarily then unhide them?

It is consistent with what @spadletskysdev found in #10225 (comment)
